Show assigned members in title of an appointment

[RealSkinnyBoy]

it would be nice to see the assigned members in title of an appointment.
For example the initials like that:

Shipped in v1.13.3 🎉

Assigned members now appear as an avatar stack (profile photo or initials, with a +N overflow when there are more) directly on the event — across the month, week, day, and agenda views, the same treatment as the Tasks list. The title truncates first so the assignment stays visible even on long event names, and the assignee names are also carried in each event's tooltip and accessible label for screen readers.

On the mobile month grid, where events collapse to colored dots, the avatars collapse with them to keep the grid readable.

Thanks for the suggestion and the mockup — it made the intent crystal clear!
