fix(proxy): resolve oidc/ pass-through credentials on every request (#44577)
* fix(proxy): resolve oidc/ pass-through credentials on every request

A pass-through credential (a use_in_pass_through deployment's api_key or
the provider's env var, e.g. TYPESAFE_API_KEY) was sent as a literal
string, so an `oidc/...` reference such as
`oidc/file//var/run/secrets/<name>/token` ended up on the wire as
`Bearer oidc/file/...`, and a rotating projected Kubernetes service
account token could not be used for pass-through auth.

Resolve credentials that start with `oidc/` through get_secret_str() on
every get_credentials() call, so the file is re-read and rotations apply
without a restart. oidc/file/ keeps its credential-directory allowlist;
other credentials are returned unchanged.

* fix(proxy): only resolve local oidc/ pass-through credentials inline

get_credentials() runs synchronously inside async pass-through routes, so
resolving oidc/google/, oidc/github/ etc. on a cache miss would make a
blocking HTTP call to the identity provider (timeout up to 600s) on the
event loop. Limit per-request resolution to oidc/file/, oidc/env/ and
oidc/env_path/, which need no network I/O; network-backed references are
left unchanged.

* fix(proxy): surface unreadable oidc/ pass-through credentials as 401

A missing or disallowed token file raised FileNotFoundError or
OidcPathNotAllowedError out of the route, which the proxy turned into a
generic 500 on every request. The resolver now raises an HTTPException
401 that names the credential reference and the reason, matching how the
pass-through routes already report an unset key.

oidc/env_path/ is no longer resolved inline because it reads any file
named by an environment variable without the oidc/file/ credential
directory allowlist; it is forwarded unchanged like the network-backed
references.
