refactor: migrate group ratio and user usable groups logic to new setting package

- Replaced references to common.GroupRatio and common.UserUsableGroups with corresponding functions from the new setting package across multiple controllers and services.
- Introduced new setting functions for managing group ratios and user usable groups, enhancing code organization and maintainability.
- Updated related functions to ensure consistent behavior with the new setting package integration.
