v0.1.2 — audit fixes

Critical:
  - DetectionService.startInForeground now passes
    FOREGROUND_SERVICE_TYPE_LOCATION OR'd with TYPE_CONNECTED_DEVICE on
    Android 14+. Without this, the system silently revoked location access
    once the screen locked, breaking DeFlock + Waze for foreground-service
    use (the whole point of the foreground service).
  - DeflockClient and WazeClient now skip JSON entries whose lat/lon parse
    to NaN. Previously NaN flowed into Location.distanceBetween, the
    NaN > limit check returned false (IEEE 754), and we submitted a
    full-confidence detection labeled "@0m" — instant false-positive RED
    from a single malformed map entry.

UX:
  - First-run permission flow auto-starts scanning after the user grants
    everything; no second tap on START required.
  - Settings shows a "Restart scan to apply" button when toggling sources
    while scanning. Source toggle changes used to silently no-op until
    the next manual stop+start.

versionCode 1 → 3, versionName 0.1.0 → 0.1.2.
