Bearer-only auth (no x-api-key) was misrouted at /v1/models and
catch-all endpoints because routing only checked x-api-key header.
Claude Code users authenticating via ANTHROPIC_AUTH_TOKEN (OAuth)
send Authorization: Bearer instead of x-api-key.
- Add is_anthropic_auth() helper detecting x-api-key, anthropic-version,
or Bearer sk-ant-* tokens
- Fix /v1/models routing to use consolidated auth detection
- Fix catch-all /{path:path} routing to recognize Bearer tokens
- Use Bearer token prefix for rate-limit key when x-api-key absent
- Add 19 tests covering auth detection, routing, and rate-limit keys
