fix(gpio): use libgpiod for input edge detection instead of lgpio

lgpio's callback delivery for alert-claimed pins was inconsistent —
delivering both directions when we'd asked for FALLING only, with the
"level" argument that supposedly distinguished them being unreliable
enough that our compensating filter sometimes dropped real edges and
sometimes let phantom ones through. The user observed gpiomon (which
uses libgpiod) showing the correct count while our service didn't.

Switch the input pin path to libgpiod (python3-libgpiod) — the same
library backing gpiomon. Each input pin gets its own LineRequest; a
background thread per pin polls read_edge_events with a short timeout
and dispatches to the user callback. Output pins continue using
lgpio because nothing was broken there.

Adds python3-libgpiod to install.sh's apt list.

Also writes the hardware-bring-up backlog (error tone, forgiving dial
timeouts, default area code) into next_steps.md so we don't lose
track while fixing dialing.
