sync: feed pane UX from private repo

- Strip kanban, grid, and saved views from ViewsOverlay (1103→631 lines)
- Add sort order dropdown (Updated/Edges/Created) with localStorage persistence
- Polish filter button, dropdown, and filter chips
- Switch to server-side dimension filtering with AND logic (dimensionsMatch=all)
- Add description preview and edge count to node cards
- Add 'created' sort option and dimensionsMatch param to types, service, API
