• Feat/usage improvements (#508)

  * i18n: update cache terminology across all languages
  
  - Change 'Cache Read' to 'Cache Hit' in all languages
  - Change 'Cache Write' to 'Cache Creation' in all languages
  - Update zh: 缓存读取 → 缓存命中, 缓存写入 → 缓存创建
  - Update en: Cache Read → Cache Hit, Cache Write → Cache Creation
  - Update ja: キャッシュ読取 → キャッシュヒット, キャッシュ書込 → キャッシュ作成
  
  Affected keys: cacheReadTokens, cacheCreationTokens, cacheReadCost,
  cacheWriteCost, cacheRead, cacheWrite
  
  * feat(usage): add cache metrics to trend chart
  
  - Add cache creation tokens visualization (orange line)
  - Add cache hit tokens visualization (purple line)
  - Add gradient definitions for new cache metrics
  - Include cache data in hourly aggregation
  - Display cache metrics alongside input/output tokens
  
  This provides better visibility into cache usage patterns over time.
  
  * fix(usage): fix timezone handling in datetime picker
  
  - Add timestampToLocalDatetime() to convert Unix timestamp to local datetime
  - Add localDatetimeToTimestamp() with validation for incomplete input
  - Fix issue where typing hours/minutes would jump to previous day
  - Validate datetime format completeness before conversion
  - Use local timezone instead of UTC for datetime-local input
  
  This resolves the issue where users couldn't fine-tune time selection
  and the input would jump unexpectedly when editing hours or minutes.
  
  * feat(usage): add auto-refresh for usage statistics
  
  - Add 30-second auto-refresh interval for all usage queries
  - Disable background refresh to save resources
  - Apply to: summary, trends, provider stats, model stats, request logs
  - Queries automatically update when tab is active
  - Pause refresh when user switches to another tab
  
  This keeps usage data fresh without manual refresh.
  
  * fix(proxy): improve usage logging and cache token parsing
  
  - Log requests even when usage parsing fails (with default values)
  - Add detailed debug logging for usage metrics
  - Support cache_read_input_tokens field in Codex responses
  - Fallback to input_tokens_details.cached_tokens if needed
  - Add test case for cached_tokens in input_tokens_details
  - Ensure all requests are tracked in database for analytics
  
  This fixes missing request logs when API responses lack usage data
  and improves cache token detection across different response formats.
  
  * style(rust): use inline format args in format! macros
  
  - Replace format!("...", var) with format!("...{var}")
  - Update universal provider ID formatting
  - Update error message formatting
  - Update config.toml generation in Codex provider
  
  Fixes clippy::uninlined_format_args warnings.
  
  * feat(proxy): enhance provider router logging
  
  - Add debug logs for failover queue provider count
  - Log circuit breaker state for each provider check
  - Add logs for missing current provider scenarios
  - Log when no current provider is configured
  - Use inline format args for better readability
  
  This improves debugging of provider selection and failover behavior.
  
  * feat(database): update model pricing data
  
  - Update Claude models to full version format (e.g. claude-opus-4-5-20251101)
  - Add GPT-5.2 series model pricing (10 models)
  - Add GPT-5.1 series model pricing (10 models)
  - Add GPT-5 series model pricing (12 models)
  - Add Gemini 3 series model pricing (2 models)
  - Update Gemini 2.5 series model ID format (use dot separator)
  - Unify display names by removing thinking level suffixes
  
  * fix(usage): correct Gemini output token calculation
  
  Fix Gemini API output token parsing to use totalTokenCount - promptTokenCount
  instead of candidatesTokenCount alone. This ensures thoughtsTokenCount is
  included in output statistics.
  
  - Update from_gemini_response to calculate output from total - input
  - Update from_gemini_stream_chunks with same logic for consistency
  - Fix from_codex_stream_events to use adjusted token calculation
  - Add test case for responses with thoughtsTokenCount
  - Update existing tests to match new calculation logic
  
  * fix(usage): correct cache token billing and add Codex format auto-detection
  
  - Avoid double-billing cache tokens by subtracting from input before calculation
  - Add smart Codex parser that auto-detects OpenAI vs Codex API format
  - Extract model name from Codex responses for accurate tracking
  
  * fix(proxy): improve takeover detection with live config check
  
  - Add live config takeover detection for hot-switch decision
  - Rebuild takeover when backup is missing or placeholder remains
  - Make detect_takeover_in_live_config_for_app public
  - Fix is_takeover_active to use actual takeover status
  
  * refactor(usage): simplify model pricing lookup by removing suffix fallback
  
  Replace complex suffix-stripping fallback with direct prefix/suffix cleanup.
  Model IDs are now cleaned by removing vendor prefix (before /) and colon
  suffix (after :), then matched exactly against pricing table.
  
  * feat(database): add Chinese AI model pricing data
  
  Add pricing for domestic AI models (CNY/1M tokens):
  - Doubao-Seed-Code (ByteDance)
  - DeepSeek V3/V3.1/V3.2
  - Kimi K2/K2-Thinking/K2-Turbo (Moonshot)
  - MiniMax M2/M2.1/M2.1-Lightning
  - GLM-4.6/4.7 (Zhipu)
  - Mimo V2 Flash (Xiaomi)
  
  Also fix test case to use correct model ID and remove invalid currency column.
  
  * refactor(proxy): improve header forwarding with blacklist approach
  
  Change from whitelist to blacklist mode for request header forwarding.
  Only skip headers that will be overridden (auth, host, content-length).
  This preserves client's original headers and improves compatibility.
  
  * fix(proxy): bypass timeout and retry configs when failover is disabled
  
  When auto_failover_enabled is false, timeout and retry configurations
  should not affect normal request flow. This change ensures:
  
  - create_forwarder: passes 0 for all timeout/retry params when failover
    is disabled, effectively bypassing these checks
  - streaming_timeout_config: returns 0 for both first_byte_timeout and
    idle_timeout when failover is disabled
  
  This prevents unnecessary timeout errors and retry attempts when users
  have explicitly disabled the failover feature.
  
  * fix(proxy): handle zero value input in failover config fields
  
  * refactor(proxy): remove retry logic and add enabled check for failover
  
  * refactor(proxy): distinguish circuit-open from no-provider errors
  
  * Align usage stats to sliding windows
  
  * feat(proxy): add body and header filtering for upstream requests
  
  * feat(proxy): enable transparent passthrough for headers
  
  - Passthrough anthropic-beta header as-is from client
  - Passthrough anthropic-version header from client
  - Passthrough client IP headers (x-forwarded-for, x-real-ip) by default
  - Filter private params (underscore-prefixed fields) from request body
  - No database changes required
  
  * feat(proxy): extract session ID from client requests for logging
  
  - Add SessionIdExtractor to parse session ID from Claude/Codex requests
  - Support extraction from metadata.user_id, headers, previous_response_id
  - Pass session_id through RequestContext to usage logger
  - Enable request correlation by session in proxy_request_logs

  * refactor(proxy): update service layer for per-app config structure
  
  Adapt proxy service, handler context, and provider router to use
  the new per-app configuration model. Read enabled/timeout settings
  from proxy_config table instead of settings table.

  * fix(proxy): resolve token parsing for OpenRouter streaming responses
  
  Problem:
  - OpenRouter and similar third-party services return streaming responses
    where input_tokens appear in message_delta instead of message_start
  - The previous implementation only extracted input_tokens from message_start,
    causing input_tokens to be recorded as 0 for these providers
  
  Changes:
  - streaming.rs: Add prompt_tokens field to Usage struct and include
    input_tokens in the transformed message_delta event when converting
    OpenAI format to Anthropic format
  - parser.rs: Update from_claude_stream_events() to handle input_tokens
    from both message_start (native Claude API) and message_delta (OpenRouter)
    - Use if-let pattern instead of direct unwrap for safer parsing
    - Only update input_tokens from message_delta if not already set
  - logger.rs: Adjust test parameters to match updated function signature
  
  Tests:
  - Add test_openrouter_stream_parsing() for OpenRouter format validation
  - Add test_native_claude_stream_parsing() for native Claude API validation
  
  * fix(pricing): standardize model ID format for pricing lookup
  
  Normalize model IDs by removing vendor prefixes and converting dots to hyphens to ensure consistent pricing lookups across different API response formats.
  
  Changes:
  - Update seed data to use hyphen format (e.g., gpt-5-1, gemini-2-5-pro)
  - Add normalize_model_id() function to strip vendor prefixes (anthropic/, openai/)
  - Convert dots to hyphens in model IDs (claude-haiku-4.5 → claude-haiku-4-5)
  - Try both original and normalized IDs for exact matching
  - Use normalized ID for suffix-based fallback matching
  - Add comprehensive test cases for prefix and dot handling
  - Add warning log when no pricing found
  
  This ensures pricing lookups work correctly for:
  - Models with vendor prefixes: anthropic/claude-haiku-4.5
  - Models with dots in version: claude-sonnet-4.5
  - Models with date suffixes: claude-haiku-4-5-20240229
  
  * style(rust): apply clippy formatting suggestions
  
  Apply automatic clippy fixes for uninlined_format_args warnings across Rust codebase. Replace format string placeholders with inline variable syntax for improved readability.
  
  Changes:
  - Convert format!("{}", var) to format!("{var}")
  - Apply to model_test.rs, parser.rs, and usage_stats.rs
  - Fix line length issues by breaking long function calls
  - Improve code formatting consistency
  
  All changes are automatic formatting with no functional impact.
  
  * fix(ui): restore card borders in usage statistics panels
  
  Restore proper card styling for ModelTestConfigPanel and PricingConfigPanel by adding back border and rounded-lg classes. The transparent background styling was causing visual inconsistency.
  
  Changes:
  - Replace border-none bg-transparent shadow-none with border rounded-lg
  - Apply to both loading and error states for consistency
  - Format TypeScript code for better readability
  - Break long function signatures across multiple lines
  
  This ensures the usage statistics panels have consistent visual appearance with proper borders and rounded corners.
  
  * feat(pricing): add GPT-5 Codex model pricing presets
  
  Add pricing configuration for GPT-5 Codex variants to support cost tracking for Codex-specific models.
  
  Changes:
  - Add gpt-5-codex model with standard GPT-5 pricing
