Add EventSeries (club-scoped): an RFC-5545 rrule + dtstart + duration and a template (kind/title/location/opponent + audience M2M). Concrete Event rows are materialised occurrences carrying a series FK plus detached/cancelled flags; the series tracks excluded_dates (EXDATEs) and a generated_until horizon watermark. Recurrence service: - occurrence_datetimes expands the rrule (via python-dateutil) up to a horizon, minus EXDATEs. - generate_occurrences materialises missing rows, copies the template + audience (so attendance syncs through the existing signals), and is idempotent. - cancel_occurrence adds an EXDATE and deletes (or soft-cancels) one occurrence so it isn't regenerated; detach_occurrence marks an occurrence as independently edited; propagate_series re-applies the template to non-detached future occurrences. - extend_event_series management command rolls the horizon forward. Register EventSeries in the admin and surface series/detached/cancelled on the Event admin. Add python-dateutil. Full suite at 100% coverage. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
