One-hour soft-lockout wrapper; display alternates 10 with underlying cause code

This code typically points to

Four ignition failures
Five flame losses in one heat call
Undesired flame
Dead blower
Unexpected gas-valve-circuit voltage

Next checks to confirm

Identify and correct alternating underlying code (11, 13, 14, 61 etc.)
Do not treat 10 as root cause by itself

Escalation

One-hour soft lockout; auto-reset after one hour

Reset behavior

Clears automatically after one hour, OR immediately if original fault is cleared and power is cycled, OR on soft lockout by cycling heat call off >2 sec but <20 sec.
