Refactor stream and template cards: collapsible groups, icon pills, compact layout

- Make picture stream groups expandable/collapsible with localStorage persistence
- Replace text labels with icon pill badges on stream and capture template cards
- Remove section description text from all tabs
- Add auto-validation on edit for static image streams
- Show full URL on static image cards instead of truncating at 50 chars
