fix(uconsole): disable GPIO 23 service (causes CM5 freeze) + open SSH

Browse Source 
GPIO 23 service used gpioset 0 23=1 on BCM2712 chip 0 instead
of the RP1 chip (base 512), writing to a critical pin and
freezing the system. Commented out until correct chip is confirmed.
SSH opened with PasswordAuthentication + PermitRootLogin for
first deployment. Lock down after initial boot.

# Internal USB Hub Enable (GPIO 23)
# The Hacker Gadgets AIO V2 board has an internal USB hub for
# the AC1200 WiFi, SDR, and other peripherals. GPIO 23 must be
# HIGH to power the hub. CM5 defaults GPIO 23 to LOW.
# Internal USB Hub Enable (GPIO 23) — DISABLED
# This service freeze the CM5 because gpioset 0 23=1 writes
# to the wrong GPIO chip (BCM2712 native, not RP1).
# Enable manually after boot once the correct chip is confirmed:
# gpioset 0 23=1 # on chip 0 (BCM2712, CORE_VOLT or critical)
# gpioset 512 23=1 # on chip 512 (RP1, likely correct)
