- Added a check for the existence of the ModuleEnableSettings table before attempting to retrieve or fixed all phase 0 create settings for an account.
- Implemented logging and a user-friendly error response if the table does not exist, prompting the user to run the necessary migration.
- Updated migration to create the ModuleEnableSettings table using raw SQL to avoid model resolution issues.
