add missing Wails bindings for ListActivityFeed, ListActivityByNode, CountActivityByNode

- migration 009: target_type, target_id, target_path columns
- new Event fields: TargetType, TargetID, TargetPath
- ListActivityFeed (paginated global), ListActivityByNode (per-case)
- all Record() callsites pass target info
- frontend: Активность sidebar section with chronological feed
- per-case Активность tab with real data (was placeholder)
- today events: clickable, target-type badges, event counts
