Add extended KNX smoke alarm support (Gira): extra fault channels, temperature, siren control, and fault acknowledge

[wlcrs]

Hi Homey team,

This PR extends the KNX smoke sensor device to support the full set of relevant group addresses exposed by Gira smoke alarm objects, beyond the previously supported smoke-only channel. All new functions are implemented as optional.

This PDF documents the newly implemented KNX objects:

What was added:

• Support for additional smoke-alarm related addresses:
  • General alarm
  • Heat alarm
  • Signal: a writable object to start/stop the siren (uiQuickAction disabled because of that)
  • Temperature
  • Battery fault
  • 230V fault
  • Smoke sensor fault
  • Temperature sensor fault
  • Fault acknowledge
• Dynamic capability handling based on configured group addresses (only show capabilities that are configured).
• Pairing and settings updates to configure all supported smoke sensor addresses in a clear order.
• Localized labels for the new smoke sensor fields.
