* fix(azure): await async azure_ad_token_provider results in the threaded wrapper
* fix(azure): keep transport params when validating async Azure client params on pydantic 2.11
* test(azure): assert the token and validation thread hops by thread identity instead of sleeps
* fix(azure): give the OIDC token exchange its own short-lived HTTP client
The exchange now runs from worker threads, so it no longer shares litellm.module_level_client's connection pool with other threads
* test(azure): check the OIDC exchange closes its client through an in-process transport
* refactor(responses): merge caller extra_headers into a new dict instead of updating validated headers in place

* test: align moved tests with rebased main
* test: carry main's legacy-file edits into moved destinations
* test: make the moved cost map fallback tests assert the fetch and the backup
The four fallback cases only checked the result was non-empty, so they still
passed with integrity validation disabled. They now inject a mock client, assert
one fetch happened, and assert the result is exactly the local backup with the
fallback reason recorded.
