Scheduler Event Timeline Presets

Switch timeline zoom between day, business-day, week, and business-week presets.

TimelinePreset controls column width and navigation step size on SchedulerTimeline.

• Hourly detail for single-day planning
• Multi-day or multi-week overviews for capacity planning

• Bind preset: RwSignal<TimelinePreset> on SchedulerTimeline.
• Let users change preset via the built-in toolbar select or set the signal from your own controls.
• Keep visible_date aligned when switching presets so the anchor day stays in view.
