Upgrade of Reports

Updated the Reports Section — working with data is now more convenient.

1. Reports are now grouped by topic, with each group clearly labeled and reports organized in a fixed order.
2. Three new reports for existing bookings — Desks, Parking places, and Meeting rooms — have been added, making it easier to get up-to-date information about current bookings.
3. Booking history reports now show a complete log of all changes made to a booking, allowing you to track all actions related to a specific booking, even if those changes fall outside the selected date range.
4. All booking history reports now include a "Duration" column, which displays the length of each booking. The value is calculated automatically and shown in HH:MM:SS format (hours, minutes, seconds).
