- On session start, insert a session_start TimerEvent so the action
appears in the activity log timeline
- Load DailySession.template via selectinload in the timeline query
so the template name is available without extra round-trips
- _to_timeline_out maps the template name into block_label for
session_start events, displaying as "Day started — Template Name"
- Add session_start to EVENT_META on the frontend (🏫 icon)
- Hide the Edit button for session_start entries since changing their
event type to a block-level action doesn't make sense
