wip: Partial KingdomService interface implementation progress

- Added missing interface method signatures to IKingdomService.cs
- Implemented missing methods in KingdomService.cs to resolve interface errors
- Fixed KingdomController.cs Forbid() method calls and parameter handling
- Added GetKingdomInfoAsync, CoordinateKvKEventAsync, OperateRoyalCouncilAsync
- Added CreateKingdomAsync, ManageMigrationIncentivesAsync merger methods
- Resolved KingdomController compilation errors with service method signatures

CURRENT STATUS: 269 compilation errors remain across other files
- Service layer interface mismatches in other controllers
- Missing repository implementations
- DTO/entity mapping issues
- Cascade errors from service layer changes

Next: Systematic error analysis and resolution across remaining files
