fix: prevent key-level metadata.tags from leaking into Bedrock passthrough body (#30985)
* fix: prevent key-level metadata.tags from leaking into Bedrock passthrough body

* test: cover bedrock key-tag litellm_metadata pre-seed in common_checks

Add a regression test asserting key-level tags on a bedrock passthrough
request land in litellm_metadata and never leak into the provider-facing
metadata field, which closes the codecov/patch gap on the auth_checks
pre-seed line. Also drop the now-stale comment that hardcoded
metadata["headers"]; the headers are written under whichever metadata
field _get_metadata_variable_name selects.

* refactor(auth): pre-seed litellm_metadata from LITELLM_METADATA_ROUTES

The auth-time pre-seed in common_checks hardcoded "bedrock", so any other
route later added to LITELLM_METADATA_ROUTES would reintroduce GH#30629 (key
tags leaking into the provider-facing metadata field) without a matching
update here. Key off the shared constant instead, and extend the regression
test to cover a non-bedrock metadata route so the route-agnostic behavior is
locked in.

* fix(auth): pre-seed litellm_metadata before header-tag merge

apply_client_tag_policy_pre_auth runs in user_api_key_auth.py before
common_checks, so it resolved get_metadata_variable_name_from_kwargs to
'metadata' (litellm_metadata was not yet present). common_checks then
pre-seeded litellm_metadata on LITELLM_METADATA_ROUTES, after which
apply_key_tags_pre_auth and _tag_max_budget_check both targeted
litellm_metadata, leaving header tags stranded in metadata and invisible
to per-tag budget enforcement on Bedrock and other matching routes.

Extract the pre-seed into LiteLLMProxyRequestSetup.pre_seed_litellm_metadata_for_route
and invoke it before apply_client_tag_policy_pre_auth so all tag merges
and the budget-check read agree on the same metadata key.

* test(auth): guard early litellm_metadata pre-seed wiring for header tags

Bugbot's autofix added a pre-seed of litellm_metadata in
_run_centralized_common_checks before apply_client_tag_policy_pre_auth, so
x-litellm-tags header tags land in litellm_metadata and stay visible to
_tag_max_budget_check on LITELLM_METADATA_ROUTES. Its test replayed that call
order in the test body, so removing the production call site still passed.

Add a wiring-level regression that drives the real _run_centralized_common_checks
and asserts header tags land in litellm_metadata (not metadata) for bedrock and
/v1/messages. Dropping the pre-seed call site now fails the test.
