After tying the ruler font to the ruler height, the labels (drawn at a
fixed H/2-1 top) sat below center because the taller font extended
downward. Shorten the ticks (major H*0.34, minor H*0.20) and center the
label in the area beneath them using TextHeight, so the digits are
vertically centered at any DPI. Applies to both the normal grid and the
FM-step grid branch.

The ruler drew labels at a fixed Font.Size := 7, so on Windows display
scaling (125/150/200%) the text no longer matched the DPI-scaled ruler
height — labels came out too small or clipped. Tie the font height to
the ruler height (-Max(8, Round(H*0.45))) so labels scale with DPI,
matching the approach used by the new bandplan overlay.

TSpectrumView remains the public facade for MainForm; waterfall, S-meter,
and ruler rendering are now in isolated units. Dead code removed.
