This update introduces a new `is_catchup_enabled` function to determine if catch-up is allowed for users based on their custom properties and system settings. The `UserViewSet` is modified to restrict admin-managed properties, including catch-up access. Additionally, various views and tests are updated to incorporate catch-up checks, ensuring that users without access receive appropriate error responses. The frontend is enhanced with a catch-up toggle in user and system settings forms, allowing for better management of catch-up capabilities.
This update introduces Redis caching for grouped settings in the CoreSettings model, improving performance by reducing database queries. A new method, `get_network_access_settings`, is added to streamline access to network settings. Additionally, the `setting_flag_enabled` function is introduced to handle boolean settings more robustly. The cache is invalidated on save and delete operations, ensuring data consistency. Tests have been added to validate the caching behavior and the new settings functionality.
