fix: BUILD_VERSION from Cargo.toml, kiosk scaling, new apps, Rust warnings

Critical:
- BUILD_VERSION was hardcoded as "1.3.0-alpha" — now reads from Cargo.toml
  This caused ALL ISOs to show v1.3.0 regardless of actual binary version

Kiosk:
- Remove --disable-gpu flags (broke display scaling on some monitors)
- Add --start-fullscreen --window-size for reliable fullscreen

New apps:
- Nostr VPN, FIPS, Routstr, noStrudel, BotFights, NWNN, 484 Kitchen,
  Call the Operator, Arch Presentation, Syntropy Institute, T-0
