fix: Resolve 500/404 cascade — JWT tenant context, wipe routes, changelog stub

Root cause: super_admin JWT returned early with no license_id, causing
@CurrentTenant() to pass undefined to every tenant-scoped service query.

- jwt.strategy: Move license lookup before super_admin early return so
  admins who own licenses get their license_id in the JWT payload
- CurrentTenant decorator: Throw 401 with clear message when license_id
  is undefined instead of letting undefined cascade into TypeORM queries
- Wipe store: Fix 6 wrong routes (/profiles → /wipes/profiles, etc.)
  and remove redundant manual license_id guards
- Changelog module: Add stub controller/service returning empty array
  to eliminate 404 on /api/changelog
- ChangelogView: Handle both array and {entries} response shapes
- AGENTS.md: Streamlined 3-tier roster (Opus/Sonnet/Haiku)
