feat(calendar-sync): add event details — attendees, organizer, status, URL

Add ICS text unescaping (RFC 5545), HTML stripping, and new fields
(attendees/status, organizer, meeting URL) to calendar-sync.el.
event-to-org now outputs org property drawers. 88 new tests across
10 test files, 146/146 pass. Also fix pre-existing test require
order and keymap guard issues.

+
+;;; Commentary:
+;; Unit tests for calendar-sync--get-all-property-lines function.
+;; Like get-property-line but returns ALL matching lines.
+;; Needed because ATTENDEE appears multiple times in an event.
+;; Covers Normal, Boundary, and Error cases.
