Fix Control4 climate crash when humidity is 'Undefined'

[frenck]

Breaking change

Proposed change

Control4 thermostats without a humidity sensor return the string "Undefined" for the HUMIDITY variable. The current_humidity property only guards against None, so int("Undefined") raises ValueError, making all climate entities permanently unavailable. The error repeats every polling cycle so entities never recover.

The fix wraps the conversion in a try/except to handle non-numeric values gracefully, returning None (unknown humidity).
