fix(build): align Kotlin/KSP/Compose and force stdlib resolution

- Use Kotlin 2.2.0, KSP 2.2.0-2.0.2, Compose Multiplatform 1.8.2 to match
  transitive dependencies compiled with Kotlin metadata 2.3.0.
- Add root resolutionStrategy force for kotlin-stdlib 2.1.20/2.1.20 variants
  to keep runtime consistent while compiler reads 2.3.0 metadata.
- Baseline ':app:assembleOssDebug' now passes, APK ~80 MB.
