Jean-Luc Makiola 65bd6c4254 feat(intent): create events from external ACTION_INSERT launches (#30)
Register an intent-filter for ACTION_INSERT on the events dir mime type
(vnd.android.cursor.dir/event), the way the AOSP calendar accepts one, so
other apps and widgets (e.g. the Todo Agenda widget) can launch Calendula
to create a new event.

MainActivity.insertFormOrNull parses the standard CalendarContract extras
(EXTRA_EVENT_BEGIN_TIME/END_TIME/ALL_DAY, Events.TITLE/DESCRIPTION/
EVENT_LOCATION/RRULE) into a prefilled EventForm via the pure, unit-tested
buildInsertEventForm — omitted fields fall back to the same defaults the
in-app "new event" uses (next full hour, +1h). The form is routed through
the existing single-event prefill channel (RootScreen → CalendarHost →
the create form for review), with calendarId left null so it resolves to
the last-used / first-writable calendar. No new permission is needed
(WRITE_CALENDAR is already held), and the user still explicitly saves.
