Fix production build crash by resolving circular import dependency

Moved database schemas from src-tauri/database/schemas/ to src/database/schemas/
to fix bundling issues and resolved circular import dependency that caused
"Cannot access uninitialized variable" error in production builds.

Key changes:
- Moved crdtColumnNames definition into haex.ts to break circular dependency
- Restored .$defaultFn(() => crypto.randomUUID()) calls
- Kept AnySQLiteColumn type annotations
- Removed obsolete TDZ fix script (no longer needed)
- Updated all import paths across stores and configuration files
