Enhance state management in DTOs and entities

- Added `States` property to `ProfileObjStateDto` and `ObjectDto`.
- Updated `MappingProfile` to include new `States` mapping.
- Made `StateId` in `ProfileObjState` required and added `State1` navigation property.
- Changed `ProfileObject` to use `States` instead of `State`.
- Cleaned up `State` class structure and removed redundant namespaces.
- Updated `ProfileObjRepository` to fetch related state data.
