Implements event overlap rendering

Adds logic to handle event overlaps in the calendar view. It introduces two patterns: column sharing for events with the same start time (rendered using flexbox) and stacking for events with a >30 min difference (rendered with reduced width and z-index).

It also introduces deep linking to specific events via URL parameters.
