feat: add iOS build workflow to GitHub Actions for streamlined release process

- Introduced a new job in the GitHub Actions workflow to build the iOS app, including steps for checking out the repository, setting up Flutter, installing dependencies, and generating Freezed classes.
- Implemented versioning logic to derive the release tag and build number dynamically based on the event type (manual or tag push).
- Added steps for setting up Xcode, installing CocoaPods, building the iOS app without signing, creating an IPA from the app bundle, and uploading artifacts.
- Enhanced release updates with the ability to handle both tag pushes and manual rebuilds, ensuring a more efficient release process.
