pyr0ball 3d47e80de6 fix: convert dial Fahrenheit input to Celsius before climate.control 
The dual-arc setpoint dial uses a Fahrenheit-range scale (60-90) to
match the Lennox reference UI, but climate.control expects Celsius
throughout this codebase. Dragging the dial was sending raw
Fahrenheit values straight into target_temperature_low/high, which
would have commanded wildly wrong setpoints on live hardware.
Also fixes a stale comment pointing at the wrong file after the
panel.yaml extraction.
