All-day improvements

The all-day section at the top of each day is core to a calendar. It’s used for all-day activities, birthday reminders, or multi-day vacation plans. And it has just gotten a whole lot better in Cron:

• Multi-day all-day events now display as wide contiguous elements across days.
• Titles use the whole width so that long event names show in full.
• “Sticky” titles fade in and out, ensuring they’re always visible when scrolling.
• Increased responsiveness and performance of the entire all-day section.
• Enables an immediate re-layout of the all-day event section when new events are added.
• Fixes to layout, copy & pasting, and toggling all-day events on/off.
