Update Android Gradle Plugin to v9 (major) (#439)

* Update Android Gradle Plugin to v9

* Finish AGP 9 migration

- Drop type parameters from CommonExtension (no longer generic in AGP 9)
  and switch the moved-off block DSL (defaultConfig/compileOptions/
  buildFeatures/testOptions) to .apply {} calls.
- Move library targetSdk to testOptions (removed from
  LibraryExtension.defaultConfig in AGP 9).
- Remove org.jetbrains.kotlin.android plugin from all modules and the
  root pluginManagement; AGP 9 has built-in Kotlin support. Drop the
  now-orphaned KotlinAndroidProjectExtension configuration block.
- Bump play-publisher 3.13.0 -> 4.0.0; 3.13.0 references the removed
  BaseAppModuleExtension.
- Remove dead consumerProguardFiles("consumer-rules.pro") references
  from curiosity and settings modules; the files never existed in git
  and AGP 9 fails the build on missing consumer rules.
