Goldens: three variants at 1x density (sv_light, sv_dark, en_light; D-098)

Drop the en_dark variant from every screenshot helper and render every
golden at mdpi (Robolectric qualifier w411dp-h<height>dp-mdpi instead of
xhdpi/xxhdpi), so a 411 x 891 dp screen is 411 x 891 px. All goldens
deleted and re-recorded; 1143 -> 865 PNGs. README describes the layout.
