C-01: Remove nginx rate limit on event invitations endpoint — was
blocking GET (invitee list) on rapid event switching. Backend
already caps at 20 invitations per event with connection validation.
C-02: respondingRef uses string prefixes (conn-, cal-, event-) instead
of fragile numeric offsets (+100000/+200000) to prevent collisions.
W-01: get_accessible_event_scope combined into single UNION ALL query
(3 DB round-trips → 1) for calendar IDs + invitation IDs.
W-02: Dashboard and upcoming endpoints now include is_invited,
invitation_status, and display_calendar_id on event items.
W-04: LeaveEventDialog closes on error (.finally) instead of staying
open when mutation rejects.
S-01: Migration 055 FK constraint gets explicit name for consistency.
S-02: InviteSearch dropdown dismisses on blur (150ms delay for clicks).
S-03: Display calendar picker shows only owned calendars, not shared.

Full-stack implementation of event invitations allowing users to invite connected
contacts to calendar events. Invitees can respond Going/Tentative/Declined, with
per-occurrence overrides for recurring series. Invited events appear on the invitee's
calendar with a Users icon indicator. LeaveEventDialog replaces delete for invited events.
Backend: Migration 054 (2 tables + notification types), EventInvitation model with
lazy="raise", service layer, dual-router (events + event-invitations), cascade on
disconnect, events/dashboard queries extended with OR for invited events.
Frontend: Types, useEventInvitations hook, InviteeSection (view list + RSVP buttons +
invite search), LeaveEventDialog, event invite toast with 3 response buttons, calendar
eventContent render with Users icon for invited events.
