🛂 (events): allow event creators to delete their own events in addition to org admins

♻️ Refactor event scope methods to separate concerns between future, current, and evergreen events

The future scope was doing too much by including evergreen events. This change separates the logic into three distinct scopes: - future: events with start_time >= from date - future_and_current: future events or events currently happening based on end_time and show_after_start_time flag - future_current_evergreen: includes evergreen events for organisation/activity/local-group contexts

Also removes future_for_map as it was identical to future after the refactor.
