Adds a bottomleft grid button (MapUtils.addGraticuleControl) to every
map in the app — Meshtastic, MeshCore, Drone, SSTV/ISS, BT Locate,
WebSDR, and Weather Satellite — defaulting to visible. The weather
satellite map's bespoke addStyledGridOverlay() is removed in favour of
the shared implementation. Also updates map-utils.css with button
styles and map-utils.js with the new addGraticuleControl() method.

All files used hardcoded rgba(74, 163/158, 255, X) values in actual CSS
rules that CSS variable overrides couldn't touch. Solution: add
--accent-cyan-rgb triplet to variables.css root/light/enhanced blocks,
then replace every rgba(74,1xx,255,) occurrence across all CSS files
with rgba(var(--accent-cyan-rgb),). Enhanced tier sets the triplet to
200, 150, 40 (amber), so tscm.css panel bg, index.css card borders,
and all other tinted surfaces go amber automatically.
