fix(more-menu): make ⋯ "Event Details" robust + non-silent (#31)

The wiring was structurally intact (menu item event-details → handler case →
handleEventDetailsAction → EventDetailsModal.open), so the failure was silent:
- handleEventDetailsAction only opened the modal `if (… && payload.video)` and
  never caught the async open() rejection — any miss = nothing happens.
- EventDetailsModal.open ran the (throwable) renderVersion BEFORE openStaticModal,
  so a render hiccup left the click looking dead.

Hardened:
- handleEventDetailsAction surfaces "No video selected" / "unavailable" instead of
  failing silently, falls back to app.eventDetailsModal, and .catch()es open().
- open() now shows the modal (openStaticModal) FIRST, then renders in a try/catch.
- The ⋯ popover is dismissed before opening the modal.

Couldn't repro by inspection, so this both fixes the likely causes and makes any
remaining failure visible (a toast / console warn naming the exact reason).
