* chore: Migrate legacy SHARED_GLOBAL permissions to SHARE and clean up orphaned fields
- Implemented migration logic to convert legacy SHARED_GLOBAL permissions to SHARE for PROMPTS and AGENTS, preserving user intent.
- Added cleanup process to remove orphaned SHARED_GLOBAL fields from the database after the schema change.
- Enhanced unit tests to verify migration and cleanup functionality, ensuring correct behavior for existing roles and permissions.
* fix: Enhance migration of SHARED_GLOBAL to SHARE permissions
- Updated the `updateAccessPermissions` function to ensure that SHARED_GLOBAL values are inherited into SHARE when SHARE is absent from both the database and the update payload.
- Implemented logic to prevent overwriting explicit SHARE values provided in the update, preserving user intent.
- Enhanced unit tests to cover various scenarios, including migration from SHARED_GLOBAL to SHARE and ensuring orphaned SHARED_GLOBAL fields are cleaned up appropriately.
