sync: multiple features from private repo

- quick-add-loading: fire-and-forget with loading placeholders, auto-open feed, SSE events, QuickAddInput redesign
- database-table-pane: TablePane + DatabaseTableView, countNodes(), event_date sort
- ui-polish-fixes: focus tab order, dim name editing, tab title sync, cost chip removal, custom sort drag-reorder, refresh button, dimension filter removal (~2,200 lines)
- node-creation-quality: description service prompt rewrite, title sanitization, extraction tool AI prompt rewrites
- feed-pane-ux: stripped kanban/grid/saved views, sort dropdown, AND dimension filtering, description preview
