fix(gpio): filter lgpio callbacks to only fire on requested edge

lgpio's gpio_claim_alert requires specifying which edges to alert on
(we use BOTH so the pin can later have callbacks for any direction).
But lgpio's .callback(... edge ...) parameter is advisory — alerts
delivered to the Python callback fire for both directions regardless.

That caused DialReader to count every pulse twice: each real falling
edge was followed by a rising edge, and both triggered the FALLING-
configured callback. Digit "4" came in as 8 pulses.

Fix is a defensive filter inside the wrapper: only invoke the user
callback when the alert's level matches the requested edge direction.
