v0.2.1 — UI polish on the map widget + Settings

- Center the OVERWATCH header (was left-aligned with the gear pushed
  by SpaceBetween — now Box-aligned so the title sits dead-center
  regardless of icon width).
- Settings + drill-down: rename the MIC source label to "COMMERCIAL"
  ("Nest, Ring, Echo devices") for clarity. Internal enum stays MIC.
- Drop the GREEN/YELLOW/ORANGE/RED text inside the threat circle and
  bump the tier scrim alpha (0.40-0.65 vs. 0.18-0.50) so the color
  reads at a glance over OSM tiles.
- Force the per-event "Open in Maps" pin to use Google Maps instead
  of whichever geo: handler the user has set as default (Waze, etc.
  could intercept). setPackage("com.google.android.apps.maps") + a
  matching <queries> entry in the manifest so it works on Android
  11+; web fallback if Maps isn't installed.
- Add a blue user-position dot at the center of the map circle, drawn
  on top of any ALPR pins.
- Auto-fit the visible map radius to max(deflockProximityM,
  citizenProximityM) via zoomToBoundingBox so the circle's edge
  literally represents the alert distance the user has chosen.
