Normalize the configured source name once in the constructor so the outer OpenTelemetryChatClient and the auto-wired inner OpenTelemetryChatClient always emit spans on the same ActivitySource. A caller passing an empty string previously produced agent-level spans on DefaultSourceName but auto-wired chat spans on the empty source, causing the chat spans to be silently dropped by exporters subscribed to the default source.
Tests added to cover the previously unexercised OTEL wiring branches:
- Ctor_NullOrEmptySourceName_AutoWiredChatClientUsesDefaultSource_Async (Theory: null and empty)
- AutoWireChatClient_PlainAgentRunOptions_PreservesContinuationToken_Async
- AutoWireChatClient_ChatClientAgentRunOptions_NoUserFactory_PreservesChatOptions_Async
- AutoWireChatClient_StreamingDisabled_DoesNotEmitChatSpan_Async
