Doesn't detect missing Express

[markjr]

Happened on two separate OSX machines (Sonoma and Sequoia), the UI Server doesn't start but thinks it did

[UI Server] > tsx-to-pdf@1.0.0 start-server
> node ConverterService/server.js
[UI Server Error] node:internal/modules/package_json_reader:268
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

✓ UI server started successfully

It's missing express, which just needs to be installed

npm i express
