Check API key

A lightweight check that the key in the Authorization header is valid, consuming no credits. This is a separate handler from GET /v1/key: it returns fewer fields (no usage_daily/weekly/monthly breakdown, no expires_at, is_management_key, or is_provisioning_key), but limit/limit_remaining now reflect this key's real per-key spend limit.

GET/api/v1/auth/key
