Allows event owners to grant individual invitees edit permission via a
toggle in the invitee list. Invited editors can modify event details
(title, description, time, location) but cannot change calendars, manage
invitees, delete events, or bulk-edit recurring series (scope restricted
to "this" only). The can_modify flag resets on decline to prevent silent
re-grant.

- C-02: flush invitations before creating notifications so invitation_id
is available in notification data; eliminates extra pending fetch
- C-03: skip RSVP notification when status hasn't changed
- C-01: add defensive comments on update/delete endpoints
- W-01: add ge=1, le=2147483647 per-element validation on user_ids
- W-04: deduplicate invited_event_ids query via get_invited_event_ids()
- W-06: replace Python False with sa_false() in or_() clauses
- Frontend: extract resolveInvitationId helper, prefer data.invitation_id

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.
