fix: remaining lint auto-fixes and rate-limit guard test fixes

- Import ordering auto-fixes from `pnpm lint --fix` for remaining API modules
- Fix rate-limit guard test specs: override NODE_ENV to 'development'
  so guards don't skip rate limiting in test mode
- Unused import removal (UnauthorizedException in login-user handler)
