Replace the turquoise with MG red tones

ev_cyan becomes a light red (#FF9A9E, for values and secondary
highlights, readable on black) and ev_cyan_deep a deep red (#3A1215,
version badge). Turquoise hardcoded in the battery card, switch track,
input panel, car outline, background glow and charging-graph grid is
replaced with matching red tones, as are two gold leftovers (tab
outline, second background glow). The mint "OK" status colour and the
amber charging curve are unchanged.
