Metal: neutral light fallbacks instead of baked-in Nord colors (F4)

Browse source 
The real draw path used Nord theme colors (0x2E3440 bg, 0xECEFF4 fg) as
fallbacks for when the frame or face is null. Those paths are effectively
unreachable, but baking a dark theme into a backend that mirrors the NS
default light theme is wrong if ever hit. Use neutral white bg / black fg
instead. The MtlView test window and the offscreen PNG render keep their
Nord palette (out of the real redisplay path), per TODO F4.
