feat: Implement sorting functionality in inspection management page

- Added sorting capabilities for equipment listings, allowing users to sort by various columns such as equipment code, name, type, and more.
- Introduced visual indicators for sort direction using icons (ArrowUp, ArrowDown, ArrowUpDown).
- Enhanced filtering logic to accommodate sorting, improving data retrieval and user experience.

These changes aim to provide users with better control over equipment data presentation and enhance overall usability in the inspection management workflow.
