Rework an event's audience: replace the single team FK with a teams M2M plus invited_members and excluded_members, and add a season FK (derived from the start date when blank) so team rosters resolve correctly. A data migration copies existing team -> teams. Add an attendance sync service: the effective audience is the union of the teams' rosters for the event's season plus invited, minus excluded; sync_event_attendances reconciles Attendance rows for future events only, adding NO_RESPONSE rows for new members and hard-deleting rows for members no longer invited. Signals drive it: editing an event or its audience re-syncs that event, and adding/removing a team-roster member re-syncs that team's future events. Register all events models in the admin (with an attendance inline) and add events to the admin registration smoke test. Add Season.covering() and pillow (Opponent.logo ImageField). Full suite at 100% coverage. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"""Signal wiring that keeps attendance in sync with the event audience.

Registered from ``EventsConfig.ready``. Two triggers:
|
|
|
|
* editing an event (its ``start``, or its ``teams`` / ``invited_members`` /
|
|
``excluded_members``) re-syncs that event;
|
|
* adding or removing a member from a team roster re-syncs that team's future
|
|
events.
