The app is purely an HTTPS API client, but the manifest left
usesCleartextTraffic implicit, which SonarQube S5332 flags (cleartext is
implicitly permitted on older Android and a merged library manifest could
re-enable it). Add an explicit network security config:
- main/release: base-config cleartextTrafficPermitted="false" (no cleartext).
- debug override (app/src/debug/res/xml): re-permits cleartext to loopback
(127.0.0.1/localhost) only, for local dev against http://127.0.0.1:3000.
This mirrors ServerUrl's rule (HTTPS required in release, HTTP allowed in
debug via allowInsecureHttp = BuildConfig.DEBUG) at the platform socket
layer. It also fixes a latent gap: at targetSdk 28+ the platform default
already blocks cleartext, so the debug loopback path only actually works
with the explicit domain-config now added.
