What changed

A new setting (off by default) to hide nearby devices that don't match any of your saved profiles from the dashboard. Useful when people around you (e.g. family) have AirPods that keep showing up at the bottom of your overview and you only want to see your own gear.

Technical Context

• Lives in General Settings → Other; persisted via DataStore, default off (behaviour unchanged unless enabled).
• UI-visibility only: scanned devices are NOT filtered out (they're still detected and counted) — only the overview's unmatched section (header card + list) is suppressed.
• Adjusted the "monitoring active" card condition so a dashboard showing only hidden unmatched devices falls back to the monitoring card instead of rendering blank.
• Enabling the setting also resets the in-session expand toggle, so the unmatched section reappears collapsed if the setting is later turned off.
