Enhance role management by adding pricing fields and updating related logic

- Updated `CreateRoleCommand` and `UpdateRoleCommand` to include optional pricing fields: `PricePerConfigPerQuarter` and `PricePerConfigPerYear`.
- Modified `RoleEndpoints` to handle the new pricing parameters during role creation and updates.
- Enhanced validation logic in `CreateRoleCommandValidator` and `UpdateRoleCommandValidator` to ensure pricing fields are non-negative when provided.
- Updated `RoleDto` and `SelectableRoleDto` to include pricing information, ensuring proper data handling in API responses.
- Adjusted frontend components to support new pricing fields in role forms and display total costs based on configurations.
- Updated API documentation to reflect changes in role management endpoints and pricing structure.
