Add APK-backed control commands

[Wheemer]

Summary

• add sync and async helpers for APK-observed control payloads
• add alarm and voice volume setters using config shadow updates
• add station mode, SOS, alarm cancel, fire drill, activation, test, light, and device mute helpers
• centralize command payload construction so station-level and device-level commands include the right fields
• use the response-backed driveway mute topic by default while allowing callers to override it

Notes

• Builds on Handle station actions and data payloads #22 and Expand APK device coverage and normalize state parsing #23, so the visible diff should shrink after those merge.
• No docs changes included.

Validation

• Parsed all xsense Python files with AST
• Ran git diff --check
• Ran mocked sync/async payload checks for station commands, volume setters, light/group commands, water/temp/driveway mutes, and action metadata
