feat: Add Fastlane configuration for mobile app deployment

- Add Fastlane scripts for iOS and Android beta/release
- Remove DID generator scripts in favor of mobile deployment
- Update .gitignore for Fastlane artifacts and reports
- Remove Android test results and build artifacts
- Increase deep link test timeout for better reliability

The changes improve mobile deployment by:
1. Adding automated deployment pipelines for iOS/Android
2. Cleaning up build artifacts from version control
3. Improving test reliability with longer timeouts
4. Removing unused DID generator scripts
5. Adding proper gitignore rules for mobile builds
