Changed action type from 'create' to 'update' in `_edit_config` for proper handling of updates. Added 'update' as a valid action in `_edit_config` logic. Also removed unnecessary print statements and standardized whitespace across migration-related files for better readability.
Standardize the use of formatted strings (f-strings) for error messages across all migration scripts to ensure correctness and consistency. Added missing blank lines across files to comply with PEP 8 style guidelines and improve code readability.
Introduce migration management tools using Peewee's migrate module. Add scripts for migration creation, application, rollback, and listing. Include initial batch of database migrations for schema and data changes.
