redshift 60921cef20 fix: allow /v1/messages/count_tokens through the proxy allowlist ...

The exact-match endpoint allowlist in the proxy omitted
`messages/count_tokens`, so every Claude Code / Anthropic SDK request was
404'd with `Path '/v1/messages/count_tokens' not found` before it ever
reached the (fully supported) forwarding path.

Add the endpoint to `_ALLOWED_ENDPOINTS` and a regression test that
pins it as always reachable on POST.

Regression history:
- 933ba105 "add missing messages endpoint" (2026-04-01): added
  messages/count_tokens handling to the forwarding layer.
- 164ed775 "support /message/count_tokens endpoint" (2026-05-09): added
  the local count_tokens handler.
- 96661384 "update not found proxy" (2026-05-14): only GET was gated, so
  POST count_tokens passed implicitly.
- 0217002e "Gate proxy forwarding behind a segment-anchored API path
  allowlist" (2026-08-23): POST gated, but the "v1/" prefix still carried
  count_tokens.
- 5af04364 "Restrict proxy forwarding to an exact method/path allowlist"
  (2026-08-24): switched to an exact table, added "messages" but omitted
  "messages/count_tokens". This is where the endpoint got locked out.
