Add options page with vector controls, whitelist, and container management

- Options page (open_in_tab) with 4 sections: fingerprint vector toggles,
  domain whitelist, container table with delete, and bulk actions
- Per-vector spoofing control: 12 independent toggles (canvas, WebGL,
  audio, navigator, screen, timezone, WebRTC, fonts, clientRects,
  plugins, battery, connection)
- Domain whitelist bypasses containerization entirely
- Delete individual containers from options UI
- Remove dead code (tabOrigins, getContainerDomain)
- Refactor profile registration into buildProfileAndRegister helper
