Change log

New endpoint that validates an API key against the registry and returns tier (free/pro) plus the key prefix (never the full key). Replaces /api/health as the credential-test target for n8n and Zapier integrations — fixes B028, where /health returned 200 to any caller and silently green-ticked invalid keys.

Fixes B003: /api/health reported 18 tools while /api/tools listed 17. Both endpoints now derive from a single registry; the missing entry (ADR LQ/EQ Check, shipped 2026-04-09) was added back. Adding a new tool propagates to both endpoints automatically.

Six endpoints migrated from camelCase to snake_case response fields (/api/unlocode, /api/uld, /api/containers, /api/vehicles, /api/consignment, /api/duty). Site-wide consistency with the other thirteen endpoints. Clean break — no dual-output. Full field rename table in CHANGELOG.md.
