Record / Convert tabs — now gated behind PUBLIC_MOBILE_APP=true. Hidden by default in VPS/dev mode; only show when explicitly opted into the mobile app build.

Edit/Upload UI — split into two concepts:
  - PUBLIC_EDIT_URL — the server base URL (empty = use proxy at /api/)
  - PUBLIC_EDIT_ENABLED=true — whether to show the edit/upload buttons at all

  bincio dev now sets PUBLIC_EDIT_ENABLED=true when instance.db exists (multi-user mode), so the upload button, edit button, and edit drawer all appear. The fetch calls already produce  correct relative URLs (${''}/api/upload = /api/upload) which the Vite proxy forwards to bincio serve.
