Implement pricing management functionality and update related components

- Added new endpoints for managing global pricing settings, including retrieval and updates for `PricePerConfigPerQuarter` and `PricePerConfigPerYear`.
- Updated `RoleService` and related commands to remove pricing fields from role management, ensuring a clear separation between role configurations and global pricing.
- Enhanced the `FactoryResetCommandHandler` to include seeding of pricing settings during a factory reset.
- Modified frontend components to support new pricing settings, including forms for creating and updating pricing information.
- Updated API documentation to reflect changes in pricing management endpoints and their expected request/response formats.
- Adjusted tests to ensure proper coverage for new pricing functionalities and their integration with existing role management features.
