When the display doesn't stay lit — any backlight mode where the screen goes
dark, including "None" — the green LED now flashes for 100 ms every 3 s, so a
dark screen doesn't leave you wondering whether the radio is still switched on.
The flash stands down whenever the LEDs are already in use: while receiving
(DMR slot RX or an analog/digital signal), while transmitting, and while muted
(which flashes the red LED instead). On standing down it restores the green LED
to the current RX state, matching the existing mute-indicator handling. Writes
go through LedWrite(), so the CPS "all LEDs disabled" option still applies.
Docs (README, MANUAL, CHANGELOG) updated.
