Scheduler Calendar Resources

Show resource rows beside the calendar grid on SchedulerCalendar.

ScheduleResource supports nested children — labels indent by depth in the resource column.

• Room, team, or equipment rows where events belong to a specific resource
• Week views that mirror timeline lane assignment without horizontal bars

• Bind resources: RwSignal<Vec<ScheduleResource>> alongside events.
• Nest sub-resources with children on each ScheduleResource.
• Set PlannedEvent.resource_id to place chips in the matching row.
