fix: update request handling to use currentQueueAuthIndex

[bbbugg]

This pull request updates the way authentication indices are handled when forwarding requests and recording usage statistics in the RequestHandler class. Instead of always using the current authentication index (currentAuthIndex), the code now consistently uses the specific authentication index associated with each request. This change ensures that requests are correctly attributed to the proper authentication context, improving accuracy in both request forwarding and usage tracking.

Key changes:

Authentication Index Handling:

• All calls to _forwardRequest and recordAttempt now use the authentication index specific to the current request (e.g., currentQueueAuthIndex or messageQueueAuthIndex) instead of the global currentAuthIndex. This ensures requests are routed and tracked using the correct authentication context. [1] [2] [3] [4] [5] [6] [7]

Method Signature Update:

• The _forwardRequest method now accepts an optional authIndex parameter (defaulting to currentAuthIndex) and uses it to select the appropriate connection for forwarding requests, rather than always using the global index.

Error Handling Improvement:

• Error messages thrown when no connection is found now reference the specific authIndex used, making debugging easier and error reporting more accurate.

Pull request overview

This PR fixes request forwarding and usage-attempt tracking to use the auth index associated with the active message queue (rather than the global currentAuthIndex), improving correctness when retries/account switching occur mid-request.

Changes:

• Forward requests and record usage attempts using currentQueueAuthIndex during streaming/retry loops.
• Pass an explicit auth index into _forwardRequest(...) and update its implementation to look up the correct WebSocket connection.
• For count-token style non-streaming requests, derive the auth index from ConnectionRegistry.getAuthIndexForRequest(requestId) and use it consistently for tracking + forwarding.
