fix(router)!: keep RPM, region, and param checks when token counting fails (#44544)
* fix(router): stop skipping rate-limit checks when token counting fails

Router._pre_call_checks() caught any token_counter() exception and
returned the full, unfiltered deployment list, bypassing the RPM,
region, and invalid-params checks for every deployment - not just the
context-window check that actually depends on the count. A content
block token_counter() cannot parse (e.g. an invalid image_url detail
value) silently disabled rate-limit enforcement for that request, with
only a log line and no error surfaced to the caller.

Now a counting failure only disables the context-window check; the
other checks still run for every deployment as before. Input-token
resolution is pulled into its own method and computed once before the
loop, so nothing needs to track "did counting fail" with a mutable
flag across iterations.

* test(router): cover the async region check when token counting fails

Replace the unit test of the private input-token resolver with a regression
test through async_get_healthy_deployments, the path the proxy uses: an
EU-pinned request whose content cannot be token-counted must not get the US
deployment

* test(router): cover the param filter when token counting fails and satisfy router coverage

* fix(router): answer 400 when no deployment takes the requested param, honor allowlists and drop_params

The pre-call param filter now reuses the router's param-acceptance helper, so allowed_openai_params,
drop_params, and additional_drop_params keep a deployment instead of filtering it out. When every
available deployment lacks a requested param, the router answers 400 UnsupportedParamsError right away
instead of a retried 429. Deployment context windows are resolved once per call.

* fix(router): keep the retried 429 when a cooling-down deployment takes the param

* fix(router): steer to a deployment that takes the param before dropping it, keep context-window fallbacks

* fix(router): steer by deployment capability, apply drop settings after region and RPM checks

A deployment-level allowed_openai_params no longer counts as taking the param when another deployment does, the drop and allow settings now apply only when no deployment that passed the region, RPM, and context-window checks takes it, and an authenticating provider is checked by its declared model instead of always passing

* test(router): make the github_copilot pre-call filter test hermetic in CI

* test(router): cover pre-call region and response_format filters through the proxy

* fix(router): judge the 400 against the request's own deployments, not a name lookup

* fix(router): judge the 400 against the passed deployments when the group name lists none

* fix(router): let a request's drop and allow settings replace the deployment's in the param check
