The DMR RX handler re-asserts the green LED whenever it reads it off, racing the
main-loop mute clear, so green flickered between the red flashes. Add a
LedGreenSuppress() hold in the LED driver: while muted the green LED is forced
off (the re-assert becomes a no-op); on un-mute the hold is released and green is
restored from the current RX state.

The mute flash forced the green LED off; on un-mute it was blanked instead of
restored, so a call in progress stayed dark. Restore green from the current RX
state (active DMR slot, or FM/digital signal received) on un-mute; the normal RX
code keeps it correct afterwards.

Treat the volume control at its minimum (lastVolume == -99, the firmware's
'muted' position) as effectively muted, so the red LED flash, the header M
and the built-in strike-through appear without an explicit SK2 mute.

Add a one-tap audio mute on the VFO and Channel screens:
- SK2 short-tap toggles mute via the built-in audioAmpMute()/audioAmpIsMuted().
The tap is only consumed by the existing "set TX TG to incoming" behaviour
while a DMR QSO is on screen, so mute works everywhere else.
- Header: a bold "M" is shown just left of the battery while muted (the
firmware's built-in strike-through over the mode text also still shows).
- LED: flashes red for 0.5s every 2s while muted (main loop), overriding the
normal RX/TX LED.

Shift the contact/TG, CTCSS/DCS and squelch info lines down by a tunable
DISPLAY_MAIN_CONTENT_TOP_PAD (4px) on MD-UV380/DM1701, so they no longer sit
flush against the new S-meter label row. Frequency and everything below are
unchanged.
