v1.0.38 - Amber login fix (Capacitor native)

- Fixed login with Amber for ZapStore/Capacitor app users
- Now uses the native nostr-signer-capacitor-plugin instead of browser
  intent URLs (which don't work inside a WebView)
- Amber opens natively as a system intent, user approves, done
- All event signing (posts, zaps, etc.) also goes through Amber natively
- Fixed Android 11+ package visibility so Amber is detected correctly
- Fixed Capacitor packages missing from package.json (prevented clean builds)
- Added SNT4EVER as community partner and friend
