Migrate Bitrise caching from deprecated branch-based to key-based

Replace deprecated cache-pull@2 and cache-push@2 steps with the new
restore-cache@1 and save-cache@1 key-based caching steps. The old
branch-based caching steps are being removed by Bitrise on 2025-04-11.

- Android workflow: cache node_modules and Gradle caches
- iOS (primary) workflow: cache node_modules, CocoaPods, and Pods
- Use checksum of example/package.json for cache key generation
- Add fallback keys (prefix-only) for partial cache restoration
