Refactor core services and components to prevent runtime errors on web platforms and optimize build environment.
- Update `Dockerfile.web` to use Node 25 for the build stage.
- Implement lazy loading for `expo-media-library` and `expo-file-system` in `ImageGallery` to prevent crashes on web where these native modules are unavailable.
- Refactor `CallKeepServiceImpl` to use dynamic imports for `expo-callkit-telecom`, ensuring the service remains compatible with web environments.
