Summary

This PR started with the intention of adding OctoberCMS, but evolved into a comprehensive standardization and improvement of the entire AppStore catalog.

Key Changes

• Added OctoberCMS: Introduced the October CMS application with a complete configuration.
• Global Appfile Standardization: Refactored all appfile.json files in the repository to strictly adhere to a unified schema. This ensures consistent field ordering, proper data types, and valid default values across the board.
• Metadata Synchronization: Updated the appfile.json for every application to accurately reflect the configurations found in docker-compose.yml.
  • Ports & Volumes: Fixed missing or incorrect port/volume mappings in appfile.json (e.g., in Adminer) by strictly syncing them with the compose definitions.
  • App Details: Refreshed taglines, overviews, and icons across multiple apps to ensure the UI displays the most accurate information.

These changes significantly improve the consistency and reliability of the CasaOS AppStore metadata.
