Fix nav classes, add detail APIs, add update-band-info skill

- Fix nav: apply .nav class and .nav-brand to logo (styles were not rendering)
- Add GET+PATCH /api/bands/:uuid and /api/artists/:uuid endpoints
  - PATCH supports append_links / append_members for non-destructive updates
- Add /update-band-info skill: fetch SNS profiles and update band description/members
