Environment & Bootstrap Stability: Fix Ghost Account and Modernize PWA Manifest

- Resolved 'Ghost Account' warning by updating layout hydration to align with V3 ID Vision (account_id vs account_id_random).
- Improved site lookup reliability using Agent API Key and structured EQ filters for exact FQDN matching (including ports).
- Modernized PWA manifest with maskable icons (PNG/WebP), app shortcuts, and unique installation IDs.
- Implemented automatic Electron 'Native' mode detection in root layout.
- Fixed stale API URLs in Launcher native file download logic.
- Added V3 migration documentation and JWT verification test scripts.
