Enhance logging for API requests and responses across executors

- Added detailed logging of upstream request metadata including URL, method, headers, and body for Codex, Gemini, IFlow, OpenAI Compat, and Qwen executors.
- Implemented error logging for API response failures to capture errors during HTTP requests.
- Introduced structured logging for authentication details (AuthID, AuthLabel, AuthType, AuthValue) to improve traceability.
- Updated response logging to include status codes and headers for better debugging.
- Ensured that all executors consistently log API interactions to facilitate monitoring and troubleshooting.

+
+**How it Works**
+
+1. **Startup:** The endpoint is parsed (respecting any scheme prefix), a MinIO-compatible client is created in path-style mode, and the bucket is created when missing.
+2. **Local Mirror:** A writable cache at `<OBJECTSTORE_LOCAL_PATH or CWD>/objectstore` mirrors `config/config.yaml` and `auths/`.
+3. **Bootstrapping:** When `config/config.yaml` is absent in the bucket, the server copies `config.example.yaml`, uploads it, and uses it as the initial configuration.
+4. **Sync:** Changes to configuration or auth files are uploaded to the bucket, and remote updates are mirrored back to disk, keeping watchers and management APIs in sync.

 The `auth-dir` parameter specifies where authentication tokens are stored. When you run the login command, the application will create JSON files in this directory containing the authentication tokens for your Google accounts. Multiple accounts can be used for load balancing.
 
-### Request Authentication Providers
-
-Configure inbound authentication through the `auth.providers` section. The built-in `config-api-key` provider works with inline keys:
-
-```
-auth:
-  providers:
-    - name: default
-      type: config-api-key
-      api-keys:
-        - your-api-key-1
-```
-
-Clients should send requests with an `Authorization: Bearer your-api-key-1` header (or `X-Goog-Api-Key`, `X-Api-Key`, or `?key=` as before). The legacy top-level `api-keys` array is still accepted and automatically synced to the default provider for backwards compatibility.

 ### Official Generative Language API
