DXcam engine overhaul:
- Remove all user-facing config (device_idx, output_idx, output_color)
since these are auto-resolved or hardcoded to RGB
- Use one-shot grab() mode with retry for reliability
- Lazily create camera per display via _ensure_camera()
- Clear dxcam global factory cache to prevent stale DXGI state
UI improvements:
- Replace "Loading..." text with CSS spinner animations
- Fix template card header gap on default cards (scope padding-right
to cards with remove button only via :has selector)
- Add auto-restart server rule to CLAUDE.md
