WGC capture fixes + high-resolution timer pacing for all loops

- Fix WGC capture_frame() returning stale frames (80k "frames" in 2s)
  by tracking new-frame events; return None when no new frame arrived
- Add draw_border config passthrough with Win11 22H2+ platform check
- Add high_resolution_timer() utility (timeBeginPeriod/EndPeriod)
- Switch all processing loops from time.time() to time.perf_counter()
- Wrap all loops with high_resolution_timer() for ~1ms sleep precision
- Add animation speed badges to static/gradient color strip cards
