fix(mobile): add expo-dev-client, pin Node version, and fix EAS build config

- Add expo-dev-client ~5.0.0 to dependencies (required for developmentClient:true profile)
- Add node: 18.19.1 to all EAS build profiles (matches .nvmrc, silences version warning)
- Add appVersionSource: local to cli section in eas.json (silences future-required warning)
- Add ITSAppUsesNonExemptEncryption: false to ios.infoPlist in app.json (eliminates App Store Connect manual config warning)
