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.
