Add diagnostic logging for temperature setpoint with no_off_system_mode TRVs

[Copilot]

Motivation:

TRVs without OFF mode support (e.g., Shelly BLU TRV) with no_off_system_mode enabled may not be setting temperature to min_temp when windows open. The existing logic should handle this, but diagnostic logging is needed to verify the setpoint is being correctly applied.

Changes:

• Added INFO-level diagnostic logging to track when no_off_system_mode logic triggers and sets temperature to min_temp
• Added detailed logging when temperature commands are sent to TRVs, including current state: window_open, hvac_mode, and no_off_system_mode flag
• Logging will help identify if temperature setpoint logic is executing correctly when windows open

Modified custom_components/better_thermostat/utils/controlling.py:

• Changed log level from DEBUG to INFO for no_off_system_mode temperature override
• Added state tracking variables to temperature set command logs

Note: Diagnostic data shows binary_sensor.windows_in_bedroom listed as "missing_entity" in issues section, which may indicate the window sensor is unavailable at times and could prevent Better Thermostat from detecting window opens.

Test-Hardware list (for code changes)

User testing required to capture logs when window opens.

Steps to test:

1. Enable INFO-level logging for Better Thermostat
2. Open configured window
3. Check logs for temperature setpoint commands and state information
4. Verify temperature is set to min_temp (typically 4-5°C)

<issue_description>

Description

I'm having trouble turning off the radiators when a window is opened. My configuration is set to 3 minutes after window opening. The auxiliary sensor for several windows is set correctly and visible in the configuration. However, BetterT shows a window icon (which I assume detects the window opening), sets the radiator to off, but the valve is still open. I don't know if this is related to the valve itself or the BT. What I found interesting is that in the diagnostic data at the very bottom, under "issues," there's information about missing entities.

Steps to Reproduce

Expected behavior:

Until the window closing time has elapsed, the valves should remain closed.

Actual behavior:

The valves are still open and heat unnecessarily.

@copilot has nothing todo with the valve position. please revert everything you did and check if the setpoint is set to 5°C if the trv has no off mode.

@copilot has nothing todo with the valve position. please revert everything you did and check if the setpoint is set to 5°C if the trv has no off mode.

Reverted all valve position logic in commit 8166ce0.

Added INFO-level diagnostic logging to track when temperature is set to min_temp for no_off_system_mode TRVs. The existing logic should already set temperature to min_temp when window opens, but I notice the diagnostic data shows binary_sensor.windows_in_bedroom listed as a missing entity, which could prevent window detection from working.

The logs will now show:

• When no_off_system_mode triggers (with min_temp value)
• When temperature commands are sent (with window_open and hvac_mode state)

This should help identify if the setpoint logic is executing correctly when windows open.
