* fix: correct Request headers format in JWT auth test
Fix test_jwt_non_admin_team_route_access by converting headers to bytes
format as required by Starlette's ASGI specification. Headers must be
bytes tuples with lowercase header names.
This allows dict(request.headers) to work correctly and enables the
authorization check to run, producing the expected error message.
* fix: ignore UUID trace_id from standard_logging_object, use litellm_call_id
The issue was that standard_logging_object.trace_id contains a UUID
(from litellm_trace_id default), which was being used instead of
falling back to litellm_call_id. This caused the test to fail because
it expected 'my-unique-call-id' but got a UUID.
Now we properly detect UUIDs (36 chars with 4 hyphens in specific positions)
and ignore them, allowing the fallback to litellm_call_id to work correctly.
This ensures we use litellm_call_id when no explicit trace_id is provided,
which gets stored in the cache and returned by _get_trace_id().
* fix: use existing_trace_id when provided instead of litellm_call_id
When existing_trace_id is provided in metadata, it should be used as the
trace_id to return (and store in cache), not litellm_call_id. This fixes
the test case where existing_trace_id is set and should be returned by
_get_trace_id().
