Outings: managing, participants, and finishing

Editing opens via the pencil on the outing page. Besides the same “What and when” and “Where” cards, two new areas appear:

1. “Participants” — the “N going · M pending” counter, the list with statuses, and the option to remove someone (the invitation is revoked and the event disappears from their calendar). Any participant can invite new people — their own contacts and their own clubs; only the organizer can remove.
2. “Management” — three actions: “Finish outing” early (track recording closes), “Cancel outing” (participants see the cancellation), and “Delete outing” — irreversible and only after canceling.
3. The route can be replaced or removed: “Participants will no longer see the track on the map”.
4. The “Save changes” button — participants see the update immediately.
