EQ sliders: put "dB" right on the value, drop the separate unit row
Previously the layout stacked "+2.5" on one row and "dB" on the next.
Reading it took an extra saccade — and the "dB" row was pure whitespace
for the column, cluttering the panel.
Now the top row of each slider column reads "+2.5 dB" as a single line
(number in the band's style, unit in muted style). The bar picks up one
more row of vertical resolution as a side effect.
