Align filter combos via shared column geometry

The genre column hid its progress sub-label by default, so its effective
height was 28px while the filter and tag columns were 46px (combo +
sub-label). Qt's default vertical centering then dropped the genre combo
~9px below the others.

Use a single _combo_column() helper for all three filters, with fixed
115px width, fixed 28px combo height, and an always-present 14px sub-row
(progress label for genres, empty spacer for filter/tag). The progress
label now toggles its text instead of its visibility, preserving the
column's reserved space.
