Deactivated WebAssembly configurations in relevant modules due to stability concerns with JS compatibility. Updated Gradle scripts to comment out related dependencies and tasks while preserving the initial implementation for future reactivation.
Enabled Wasm target across all relevant modules and removed conditional enablement logic. Refactored `core:core-utils` to move JVM-specific code to a new `backend:infrastructure:persistence` module for strict KMP compliance. Updated dependencies, adjusted Gradle configurations, and resolved circular dependencies.
Removed redundant `jvmToolchain(25)` declarations across module build scripts, as the JVM toolchain is now managed centrally. Added comments for clarity.
