fix(cw): restore app label, fix R8 code stripping, force 32-bit ABI

Three release-breaking issues found in the v4.5.0 APK (app crashed on
launch, label showed "Morse Expert", dex shrank to 282KB vs 3.5MB):
1. app_name: the ported app_values.xml shipped a "Morse Expert"
   app_name string which overrode Look4Sat Pro's label during resource
   merging - removed (no other string collisions).
2. R8 stripped nearly all code: the in-app sun.misc.Unsafe/Cleaner
   stubs clashed with android.jar library classes. Moved stubs to
   com.rtbishop.look4sat.feature.cw.suncompat and updated k3.d/s/r
   imports (k3.r keeps the reflective Class.forName("sun.misc.Unsafe")
   string, which returns null on Android hidden-API limits).
3. proguard-rules.pro added (AGP 9 variant-level
   CanProduceConsumerProguardFiles): keep pas.** (JNI RegisterNatives
   resolves by class name) plus all ported CW classes.
4. app-level ndk abiFilters forced to armeabi-v7a: the ported
   libnativedecoderjni.so is v7a-only, so a multi-ABI APK would crash
   with UnsatisfiedLinkError on arm64 devices.

Verified: :feature:cw:compileDebugKotlin BUILD SUCCESSFUL.
