fix: Yaesu panel — S units, sidebands, three-step ATT, readable sliders, own tab

First look on the FTDX10 turned up six things:

The S meter printed a raw percentage — "57" tells an operator nothing, and it is
the S number that goes into a report. It now reads S1-S9/S9+dB, the same value
the click-to-fill RST already used.

CW, RTTY and the data modes exist on BOTH sidebands and the operator is the one
who knows which they want. The buttons now carry the rig's actual sideband and a
double-click flips it; PSK is added, riding the rig's DATA mode as it does on the
radio itself. This also means the mode row drives the rig directly (MD0 with the
exact mode) instead of going through the ADIF path, which could only pick a
sideband by convention.

The attenuator is a 6/12/18 dB pad on these rigs, not the single step I assumed —
two thirds of the control was unreachable.

Sliders had no visible filled side: --muted is barely lighter than the card it
sits on, so the whole track read as one bar. They also came in three kinds (two
bare range inputs among them). One component now, explicit track colour, and it
takes a min/max so power in watts and DNR 1-15 look like the rest.

The panel stretched across the whole window; it is a column of controls, so it is
now capped and every row stays readable.

And it gets its own Yaesu tab, like FlexRadio and Icom, rather than only being
available as a Main-view pane.
