Replace collapsible stream groups with sub-tabs navigation

- Replace expandable/collapsible groups with tab bar (Screen Capture, Static Image, Processed)
- Persist active stream tab in localStorage
- Shorten tab labels by removing "Streams" suffix
- Remove type badge from cards (redundant with tab separation)
- Add count badge on each tab with active highlight
