Glass panels: MFD phosphor green (21FF42) + respect BT_COCKPIT_TINT

Browse Source 
The BT_GLASS_PANELS=1 per-display windows tinted the mono MFD surfaces pure
WHITE (MfdMonoTint 0x00FFFFFF) -- the cockpit surround already used phosphor
green via BT_COCKPIT_TINT (L4VB16 CkTint).  New GlassMfdTint(): default the
standard green rgb(33,255,66)=0x0021FF42, overridable by the SAME
BT_COCKPIT_TINT=RRGGBB env the surround honours (used verbatim as the
0x00RRGGBB ExpandPlaneToBGRA tint -- no R5G6B5 packing, which is the
surround's D3D path).

Pixel-verified live (BT_GLASS_PANELS=1): all lit interior MFD pixels
R33 G255 B66 = 21FF42 by default (was white); BT_COCKPIT_TINT=FF8000 ->
R255 G128 B0.  Radar keeps its amber palette (monoTint -1, unchanged).
