feat(events): add calendar date visual to My Tickets

Replaces the My-tickets filter that lived on the removed calendar page.
A calendar button opens the date-picker popup with per-day dots over the
user's own events; picking a day filters the ticket list to it (a
removable date chip overrides the upcoming/past toggle while active).
