fix: resolve TypeScript build configuration errors

- Disable allowImportingTsExtensions in tsconfig.server.json
  (only allowed when noEmit is true)
- Remove server execution from build:server script
  (build should only compile, not run)
- Fix build process to successfully compile both server and client
