fix(i18n): translate visual preset parameter sliders

The slider labels (Sensitivity, Bloom, Pixelation, …) live in the shader
modules and were rendered raw, so they stayed English in every locale.
Mark them with msg() and render them through t(); add es and ru entries.
WHOT/BHOT and Ironbow keep their names. Russian Bloom is now «Свечение».
