What this fixes:
On boot, if PipeWire/Pulse starts with the sink at ~40%, LVA now pushes the sink volume to match the persisted LVA volume (0.0–1.0).
When you move the HA media_player volume slider, LVA now updates:
wpctl (PipeWire) if available
pactl (PulseAudio / PipeWire-Pulse) if available
amixer (ALSA) as a fallback
No reboot / alsactl store required — LVA simply re-applies the persisted volume at start.
Added a new ButtonConfig dataclass:
enabled: bool = False
pin: int = 17 (BCM pin for the button)
long_press_seconds: float = 1.0
Extended the main Config dataclass with a button: ButtonConfig field.
Updated load_config_from_json() to construct button_config from the "button" section in config.json.
This allows enabling/disabling the button, changing the GPIO pin, and tuning the long-press threshold (and optional poll interval) without code changes.
Adds new dataclasses (AppConfig, AudioConfig, LedConfig, etc.) to define the application's configuration structure. Includes a load_config_from_json() helper to parse the JSON file and provide default values for any omitted sections
