Add Agenda “fresh start” action that archives active events

[Copilot]

Users need a one-click “start over” flow in Calendar/Agenda that clears visible events without deleting history. This change adds that reset action and moves existing events into an archive state so they remain recoverable.

• What changed

  • Added soft-archive support for agenda events via archived_at.
  • Added a bulk archive operation for a user+agenda (archive_all_agenda_events/2).
  • Updated active event listing to exclude archived rows.
  • Added a new Agenda UI action/button (fuck this) with confirmation, wired to archive all current events and reset the LiveView stream.

• Data model

  • New nullable column on agenda_events:
    • archived_at :utc_datetime

• Behavioral flow

  • Triggering fresh start:
    1. Set archived_at for all currently active events in the user’s agenda.
    2. Clear the rendered event stream so the user starts with an empty agenda view.

• Focused tests added

  • Context test verifies archived events are excluded from active listings.
  • LiveView test verifies clicking the button clears the list and persists archive state.

def archive_all_agenda_events(user_id, agenda_id) do
  now = DateTime.utc_now() |> DateTime.truncate(:second)

  from(ae in AgendaEvent,
    where:
      ae.agenda_id == ^agenda_id and ae.user_id == ^user_id and is_nil(ae.archived_at)
  )
  |> Repo.update_all(set: [archived_at: now])
end
