Fix TemperatureAPI making API calls and showing unhealthy when disabled

[Copilot]

TemperatureAPI continued polling the Open-Meteo endpoint even after toggling temperature_enable off via the UI, and the component incorrectly reported as unhealthy in the dashboard.

Two bugs:

• Stale enable flag: run() read self.temperature_enable cached at init time (from apps.yaml). A UI toggle writes to an HA entity state, not apps.yaml, so the cached value was never updated and polling continued regardless.
• Missing health timestamp: When temperature_enable=False, run() returned early without calling update_success_timestamp(). The health check considers any component with no success update in 60+ minutes as dead, triggering the "Demand (unhealthy)" banner.

Fixes (temperature.py):

• Re-read temperature_enable live on every run() call via get_arg(), so UI toggle changes take effect without a restart:

  temperature_enable = self.get_arg("temperature_enable", self.temperature_enable)
  if not temperature_enable:
      self.update_success_timestamp()  # keep health check green
      return True

Test updates (tests/test_temperature.py):

• Added get_arg() to MockTemperatureAPI to satisfy the dynamic lookup.
• Updated _test_run_disabled to assert that update_success_timestamp() is called when the component is disabled.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
