v0.1.3 — DeFlock via Overpass + per-source health UI

Browse Source 
The cdn.deflock.me CDN is gated behind Cloudflare bot mitigation that
mobile HTTP clients can't pass. The live deflock-app Flutter client
abandoned that path; it POSTs Overpass-QL queries directly to
overpass.deflock.org (with overpass-api.de as a fallback). Verified by
hitting the same endpoint from curl — 22 ALPRs returned for the
Springfield VA bbox, matching the user's screenshot of the working app.

DeflockClient rewrite:
  - POST [out:json][timeout:25];(node[surveillance][type=ALPR](bbox););out body;
  - 5 km half-width bbox around the user
  - 24h on-disk cache keyed by 0.05° grid cell (revisits don't refetch)
  - Returns sealed FetchResult: Success(points) | Failed(reason)

DeflockScanner update:
  - Replaces 20° tile concept with distance-based refetch (1.5 km threshold)
  - Records SourceHealth on each fetch outcome

Waze: reCAPTCHA gating confirmed. WazeClient.fetchPoliceNear now returns
sealed FetchResult; WazeScanner records SourceHealth.FAILED with
"Upstream blocked (HTTP 403)" so the user sees why no Waze data is
flowing instead of silent zeros.

New fusion/SourceHealth.kt — per-source MutableStateFlow registry,
record(source, ok, message) + reset() called on service start/stop.

UI: SourceRow in the bottom-sheet drill-down now shows the health
message in orange when status = FAILED instead of "no detections".

versionCode 3 → 4, versionName 0.1.2 → 0.1.3.
