feat: brain masonry card grid — Karakeep-style layout with Atelier aesthetics

- 3-column CSS masonry grid (2 on tablet, 1 on mobile)
- Link cards show screenshot thumbnails
- Note cards show content body inline
- Tags as pills, folder/date in meta footer
- Screenshot serving endpoint added to brain API
- Auto-polling for pending items (3s interval)
- Detail sheet shows raw_content for notes
- Warm frosted glass card styling matching Atelier design
