ICSProvider parses .ics files (icalendar library) and creates local
CalendarEvents, skipping duplicate UIDs. Export builds an iCalendar
from events in a date range, deduplicating recurring event
occurrences back to a single VEVENT with RRULE. REST endpoints:
POST /import-ics (multipart upload), GET /export-ics (download).
