feat(register-and-statistics): enhance role management logic (#register-and-statistics)

- Refactored CreateRole and UpdateRole functions to handle default role.
- Added dynamic role assignment logic in 'role.go' using conf settings.
- Improved request handling in 'handles/role.go' with structured data.
- Implemented default role logic in 'db/role.go' to update non-default roles.
- Modified 'model/role.go' to include a 'Default' field for role management.
