Configure EAS Build and fix expo-doctor issues

- Add eas.json with development, preview, and production profiles
- Link project to EAS (projectId: 93c75cae-fecf-4ce5-8cd8-c823760b12e2)
- Add expo-dev-client, expo-constants, expo-linking dependencies
- Remove eas-cli from project deps (use globally)
- Add ITSAppUsesNonExemptEncryption to iOS infoPlist
- Use catalog react with expo.install.exclude to skip version check
- Fix slug to match EAS project registration
- Run pnpm dedupe to resolve duplicate react across workspaces
