- Read user profile from Logto ID token in OrgResolver, store in
  Zustand org store, display in sidebar footer and TopBar avatar
- Fix license limits showing "—" by aligning frontend LIMIT_LABELS
  keys with backend snake_case convention (max_agents, retention_days,
  max_environments)
- Bump @cameleer/design-system to v0.1.38 (font-size floor)
- Add dev volume mount for local UI hot-reload without image rebuild
