Separated dnd-kit drag handlers (attributes/listeners) from ListItemButton
to ListItemIcon only. Previously, long-press or rapid clicks on nav items
would trigger drag detection and cancel the click event, causing the item
to visually highlight but fail to navigate.
Changes:
- Moved sortable attributes/listeners to icon elements only
- ListItemButton now handles pure navigation clicks without interference
- Drag handle cursor ('grab') remains on icons when sortable is enabled
Fixes issue where sidebar tabs would "go dark" without actual route change.
- Consolidated and reordered imports in various files for better readability and maintainability.
- Removed unused imports and ensured consistent import styles.
- Enhanced the structure of components by grouping related imports together.
- Updated the layout and organization of hooks to streamline functionality.
- Improved the overall code quality by following best practices in import management.
