Auto-populate activity log from timer events with edit and delete

- New GET /api/logs/timeline endpoint joins TimerEvent with block/subject/session data
- New PATCH and DELETE /api/logs/timeline/{id} endpoints for editing/removing events
- LogView redesigned as a chronological timeline grouped by date
- Edit inline: timer events support type + time correction; notes support text edit
- Delete works for both auto events and manual notes
