fix(caching): closer conn check if the request is Chunked and EOF drop cache

[sendya]

This pull request introduces improvements to the caching logic and expands the mock server's test endpoints. The most significant changes are related to better handling of incomplete chunked uploads and the addition of a new endpoint for testing chunked responses.

Caching logic improvements:

• Updated the flushbufferSlice function in caching.go to discard incomplete chunked file uploads by calling DiscardWithMessage if the end of file (eof) is not reached and the response is chunked. This helps prevent storing incomplete or corrupted cache entries.

Testing enhancements:

• Added a /chunked endpoint to the mock server in main.go that serves data using a rate-limited reader, enabling more robust testing of chunked transfer encoding scenarios.
