feat(passthrough): add configurable pass-through request timeouts (#30266)
* feat(passthrough): add configurable pass-through request timeouts

Allow operators to set general_settings.pass_through_request_timeout and per-endpoint timeout values, and apply them to native HTTP passthrough routes and SDK passthrough paths such as Bedrock /converse.

* fix(passthrough): address CI lint and regenerate dashboard API types

* refactor(passthrough): extract timeout utils to proxy-free module, fix router_timeout drop

- Move resolve_llm_passthrough_timeout + resolve_pass_through_request_timeout to
  litellm/passthrough/timeout_utils.py (no fastapi/proxy imports at module scope)
- router.py and passthrough/main.py now import from timeout_utils directly,
  avoiding the fastapi transitive import in pure SDK contexts
- pass_through_endpoints.py re-imports from timeout_utils for backward compat
- resolve_llm_passthrough_timeout now accepts router_timeout so Router(timeout=X)
  is respected for passthrough calls instead of being silently dropped
- Use _get_httpx_client (cached) instead of bare HTTPHandler(...) in sync path
  to avoid creating an unclosed client per call

* fix(router): use _explicit_timeout for passthrough to not shadow general_settings

self.timeout defaults to litellm.request_timeout (6000s) when the user
doesn't pass timeout= to Router(). Using it as router_timeout caused
general_settings.pass_through_request_timeout to be silently ignored.

Only pass router_timeout when the user explicitly set Router(timeout=X).

* fix(timeout_utils): avoid fastapi transitive import by using sys.modules

resolve_pass_through_request_timeout previously did a lazy
`from litellm.proxy.proxy_server import general_settings` which loads
the proxy module (and transitively fastapi) even in pure SDK contexts.

Replace with a sys.modules lookup: if the proxy module is already loaded
(i.e. we're inside the proxy), read general_settings from it; otherwise
skip and fall back to the 600s default. No import is triggered.

* fix(lint): remove unused imports from pass_through_endpoints.py

DEFAULT_PASS_THROUGH_REQUEST_TIMEOUT_SECONDS and resolve_llm_passthrough_timeout
are not used in this file; only resolve_pass_through_request_timeout is.

* fix(pass_through_endpoints): re-export DEFAULT_PASS_THROUGH_REQUEST_TIMEOUT_SECONDS

Tests import this constant directly from pass_through_endpoints.py;
re-add it to the import from timeout_utils for backward compatibility.

* fix(pass_through_endpoints): re-export resolve_llm_passthrough_timeout for backward compat

Tests import both DEFAULT_PASS_THROUGH_REQUEST_TIMEOUT_SECONDS and
resolve_llm_passthrough_timeout from pass_through_endpoints.py; use
noqa comments to suppress the unused-import lint warning on re-exports.
