feat: view groups (#7176)

Fix #4244 and #4356

This pull request introduces the new "view groups" capability, enabling
the reordering, hiding, and showing of columns in Kanban mode. The core
enhancement includes the addition of a new entity named `ViewGroup`,
which manages column behaviors and interactions.

#### Key Changes:
1. **ViewGroup Entity**:  
The newly added `ViewGroup` entity is responsible for handling the
organization and state of columns.
This includes:
   - The ability to reorder columns.
- The option to hide or show specific columns based on user preferences.

#### Conclusion:
This PR adds a significant new feature that enhances the flexibility of
Kanban views through the `ViewGroup` entity.
We'll later add the view group logic to table view too.
