Update all classname mappings

### **Description**
Update all classname mappings in the **MetaMask Design System** to follow the standardized naming conventions:

- **For Tailwind class mappings:** `TWCLASSMAP_COMPONENTNAME_FROM_TO`
- **For general mappings:** `MAP_COMPONENTNAME_FROM_TO`

This will improve consistency and readability across the codebase.

### **Technical Details**
- Refactor all existing classname mappings to follow the new format.
- Ensure all instances of mappings are updated throughout the codebase.
- Verify that no functionality is affected after the renaming.
- Update documentation or comments where necessary to reflect these changes.

### **Acceptance Criteria**
- All classname mappings follow the new naming conventions.
- No broken references or regressions occur due to renaming.
- Documentation and code comments are updated accordingly.
