v0.2.0 — live map circle + MIC detection (Echo/Ring/Nest/hidden cams)

- Replace the static threat circle with an osmdroid-backed map
  centered on the user, with red ALPR pins and a tier-color scrim.
  Falls back to the muted gradient when idle or before the first
  location fix arrives.
- Add DetectionSource.MIC: BLE/WiFi candidate path for Amazon
  Echo/Ring (Lab126 OUIs + AVS service UUID 0xFE03), Google Nest/
  Home/Chromecast (Google OUIs + mfg id 0x00E0), and generic
  Chinese hidden-cam vendors. Score capped at 84 (ORANGE) so RED
  stays reserved for ALPR/Axon-grade evidence. Toggleable in
  Settings; piggybacks on the BLE+WiFi scanners — no new radio.
- Drop the "[DЯΣΛMMΛKΣЯ]" stylized branding for a clean OVERWATCH
  header (notification channel + app label updated to match).
- Fix DeFlock geo-pin tap doing nothing: resolveActivity returns
  null on Android 11+ without a <queries> entry even when Maps is
  installed. Drop the pre-check, try/catch ActivityNotFoundException,
  fall back to a maps.google.com URL if no geo: handler exists.
