fix(fdroid): drop Google Play Core so the scanner accepts the APK; prep v0.1.15

F-Droid's APK scanner rejected v0.1.14: 6 com.google.android.play.core.*
(SplitInstall/SplitCompat/tasks) references. They came from Flutter's
io.flutter.embedding.engine.deferredcomponents.PlayStoreDeferredComponentManager
being pinned by our over-broad '-keep class io.flutter.** { *; }' ProGuard
rule — Tane uses no deferred components, so R8 should shrink that manager
away (as it does for immich and other Flutter F-Droid apps, which don't
carry such a keep). Narrow the keep to io.flutter.plugins.**; JNI-critical
embedding classes (FlutterJNI, …) stay via the embedding AAR's own consumer
ProGuard rules — verified the built APK still contains FlutterJNI and no
com.google.android.play.core.* at all. Also exclude the com.google.android.play
group at the dependency level (belt-and-suspenders) + -dontwarn.

Bumps to 0.1.15 (+17); fdroid recipe versionCodes 171/172/173.
