Backup does not fully restore installed plugins and their specific settings/sources

Steps to reproduce

1. Open Cloudstream and add a repository.
2. Install multiple plugins from the repository.
3. Configure specific settings, preferences, or custom sources for some of these plugins.
4. Create a backup using the app's built-in backup feature.
5. Uninstall the app and perform a fresh installation.
6. Restore from the previously created backup file.
7. Navigate to the plugins/extensions section.

Expected behavior

The restore process should completely replicate the previous state of the app. This includes:

• Restoring the added repositories.
• Automatically reinstalling all previously installed plugins.
• Restoring all plugin-specific settings, configurations, and sources.

Actual behavior

The restore process only adds the repositories back to the app. None of the plugins are installed, and all plugin-specific settings and sources are missing. The user is forced to manually browse each repository, identify which plugins were previously installed, reinstall them, and manually re-enter all specific settings and sources.

Acknowledgements

• I am sure my issue is related to the app and NOT some extension.
• I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.
• I have written a short but informative title.
• I have updated the app to pre-release version Latest.
• I will fill out all of the requested information in this form.

Start by locating the built-in backup and restore flow, then compare the repository restoration path with how installed plugins and their settings and sources are persisted. Done means a fresh installation restored from a backup reinstalls the previously installed plugins and reproduces their plugin-specific settings and sources.
