[FrekiManagarm]

TL;DR

Replaced FullCalendar with custom components for a new timetable implementation using @devexpress/dx-react-scheduler.

What changed?

• Removed FullCalendar implementation from calendar.tsx
• Added new components for timetable functionality:
  • Appointment components (content, component, layer)
  • Day scale components (cell, layout, row)
  • Timetable components (cell, layout, row)
  • Main layout component
• Updated timetable-page.tsx to use the new calendar component
• Added @devexpress/dx-react-core and @devexpress/dx-react-scheduler dependencies

How to test?

1. Navigate to the timetable page
2. Verify that the new timetable layout is displayed correctly
3. Check that day scale and timetable cells are rendered properly
4. Ensure that appointments can be added and displayed (if implemented)

Why make this change?

This change aims to provide a more customizable and flexible timetable solution using @devexpress/dx-react-scheduler. It allows for better control over the appearance and functionality of the timetable, potentially improving performance and user experience.
