Adds work week configuration feature

Implements configurable work week presets, allowing users to customize the days displayed in the calendar.

This includes:
- Defining work week settings (work days, day names, total days).
- Providing predefined work week presets (standard, compressed, weekend, full week).
- Adding UI elements to switch between presets.
- Updating grid and header rendering logic to reflect the selected work week.
- Emitting events when the work week changes, triggering necessary UI updates and data re-renders.

This provides a more flexible and personalized calendar experience.
