fix(proxy): forward a valid metadata.user_id to Anthropic Messages on pass-through routes (#49333)
* fix(proxy): forward the client's own metadata on Anthropic and custom pass-through routes

* fix(proxy): forward only a valid metadata.user_id to Anthropic Messages on pass-through routes

The whole-object forward sent keys Anthropic refuses and reached other
providers, so a request that used to pass could start failing with a 400.
Read the client's user_id after hooks, drop it unless it is a string with no
email or phone number, and send only that key when the upstream URL path ends
in /v1/messages. Share the validator with the translated route, whose email
check now matches any embedded address as Anthropic's does.

* fix(proxy): forward metadata.user_id only to Anthropic upstreams no guardrail scans

Limit the pass-through user_id to Messages create on api.anthropic.com or the
configured Anthropic base, mirror the checks Anthropic answers 400 for, and keep
the field off any request a pre-call guardrail inspects. The translated route
goes back to its own user_id filter.

* fix(proxy): judge user_id forwarding on the whole request and cap it for configured Anthropic bases

* refactor(proxy): pass the user_id check a plain mapping instead of an optional body

* fix(proxy): drop an unprintable metadata.user_id and warn when a refused id is dropped

Anthropic's whitespace is not Python's, so a control character before the at sign hid an email from the filter and turned a 200 into a 400. Fireworks and Moonshot also fail on newline ids. Requiring a printable id covers both, and a refused id now logs a warning that never carries the value.
