Merge PR #80: feat(perm) fine-grained account permissions

Conflict resolution + cross-PR integration:
- player.ts: kept #88's POST /:botId/fm route AND gated it with
  requirePermission('player.control') so the new control endpoint honors #80's
  permission model (it was added without gating).
- bot.ts: kept #81's relocated /settings routes (the relocation fixes the GET
  /settings shadow bug) and dropped #80's now-duplicate bottom copy; gated
  POST /settings with requirePermission('bot.manage').
- Navbar.vue: composed #82's dedicated-link scope with #80's permission filter —
  displayedBots is now the INTERSECTION (scope ∩ controllable allow-list).
- database.ts: kept BOTH new table sets (#87 favorite_playlists + #80
  user_permissions/user_bot_access).
- bot.test.ts: updated to createRequireAuth(sessions, permissions) for #80's new
  two-arg signature.

#80 review fixes (credential exposure / IDOR, adversarially verified):
- GET /:id/config now requires bot.manage + bot access AND redacts ts6ApiKey +
  identity from the response (was readable by any authenticated member).
- GET /:id and GET /:id/avatar now require bot access (were ungated read oracles).
