fix: resolve TypeScript type errors across codebase

- Add experimentalDecorators support in tsconfig.node.json for TypeORM entities
- Fix mssql module import in order-resolver.ts (static vs dynamic import)
- Extend ISqlType parameter types in sql-server.ts for NVarChar compatibility
- Fix variable naming and type assertions in bip-users-dao.ts
- Add proper type assertions for IPC call results in renderer hooks
  (useAuth, useCleaner, useExtractor, useValidation)
- Add definite assignment assertions in config-manager.ts
