* feat(proxy): total_timeout bounds a whole non-streaming request
A `total_timeout` body field or `x-litellm-total-timeout` header (the header wins) gives a non-streaming
/v1/chat/completions, /v1/messages or /v1/responses request one budget for preparation, retries,
moderation and post-call processing. Past it the proxy answers 408 and cancels the upstream call, and
a retry whose backoff cannot fit ends early with the error it would have retried. A body value on a
streaming or background request is refused with a 400, a header value leaves it unbounded. A timed out
request is billed like a client disconnect.

* fix(proxy): ignore any total_timeout header on requests it cannot bound, and never interrupt pre-call admission
A globally configured x-litellm-total-timeout that is malformed no longer fails the streaming and
background requests it is ignored on. The deadline holds while pre-call admission runs, since admission
reserves shared quota before it records it, and an expired deadline then ends the request before
dispatch, where the failure path hands the reservation back.

* fix(proxy): a total_timeout cuts slow pre-call hooks short, holding only the rate limit reservation

Code outside the router now reaches it only through the entry points
(registry, settings, health, select, apply, observe, register_plugin, retire)
or the endpoint methods; the outside-member allowlist shrinks from 139 to 45.
litellm/router.py no longer imports litellm.proxy: it asks the installed
RouterHost (litellm/router_host.py) for vertex pass-through credentials,
member auto-router authorization and auto-router prompt compression, and the
proxy installs its host on import. Call sites where a model name can be
missing keep the old answer instead of reaching an entry point with None.
* fix(proxy): return 400 instead of 500 for missing required params and invalid pagination
