Add recent events and stats to eggs, feed, and move forms

- Create recent_events.py helper for rendering event lists with humanized
  timestamps and deleted event styling (line-through + opacity)
- Query events with ORDER BY ts_utc DESC to show newest first
- Join event_tombstones to detect deleted events
- Fix move form to read animal_ids (not resolved_ids) from entity_refs
- Fix feed purchase format to use total_kg from entity_refs
- Use hx_get with #event-panel-content target for slide-over panel
- Add days-since-last stats for move and feed forms
