Session: redesign result cards, saved queries always visible, collapsible sections

- Move all action buttons (star, expand, JSON, trash) into each result card header
- Always show query text in result cards (no conditional hiding)
- Saved queries section permanently visible above results, collapsible via chevron
- Result cards collapsible via per-card chevron toggle
- Add drop shadow and remove border around query text
- Clear query field after execute; tap result query label to reload it into editor
- WebView re-renders HTML on App.ThemeChanged for instant dark/light switch
- Result card trash, delete result, save/load query, open graph/table all work per-card
