Allow hiding weekends or specific weekdays in new Schedule month view

[anderbytes]

Please add support in Mantine Schedule month view for hiding weekends, or more generally, hiding specific days through an array-based configuration.

Problem

At the moment, month view appears to always render all seven weekdays. In many business and operational use cases, weekends are not relevant and end up consuming unnecessary space.

There are also scenarios where consumers may want to hide only specific days, depending on local business rules or product-specific scheduling logic.

Proposed:

A flexible solution could support both:

• A simple boolean prop such as hideWeekends
• A more generic prop such as hiddenWeekDays, accepting an array of weekday indexes

Example: hide weekends

<MonthView
  hideWeekends
/>

Example: hide specific weekdays

<MonthView
  hiddenWeekDays={[5, 6]}
/>

Expected Behavior

• Hidden days should not be rendered in the month grid
• The calendar layout should automatically reflow based on the visible days
• Weekday headers should reflect only the visible days
• Event rendering and navigation should remain consistent
• Consumers should not need to preprocess data or build a custom month view to achieve this behavior

Use Cases

• Workweek-only scheduling interfaces
• Internal business tools where weekends are irrelevant
• Regional or domain-specific calendars with non-standard visible days
• Cleaner month layouts with better horizontal space usage
