fix: sweep final hardcoded cyan from mode JS files and CSS

- proximity-radar.js: fix missed dot stroke in new-device creation path
- gps.js: GPS constellation color via object getter; globe atmosphere reads CSS var
- websdr.js: globe atmosphere, map markers, popup buttons, point label use CSS var
- subghz.js: canvas strokeStyle reads --accent-cyan
- sstv.js: ISS track polyline reads --accent-cyan
- app.js: info message border-left uses var(--accent-cyan)
- subghz.css, gps.css: replace all #00d4ff with var(--accent-cyan)
