wkw2k/HDC-Releases ? reverse-engineered prompt

Build me a Windows app for .NET 8 that connects Hapak ERP with DocBox and automatically moves documents between the two systems.

It should watch a hot folder for incoming PDFs, read the filename to figure out the document type, then send the file to the right folder in DocBox using the API. It also needs to connect to a PostgreSQL database for Hapak, support a fallback folder when something can’t be matched, and run reliably in the background like a Windows service.

I also want a simple modern Windows interface where I can load a license, check the configuration, start and stop the services, and see status and logs. Include automatic update support from GitHub releases, basic monitoring, and secure handling of config values like passwords and API keys. Please make it easy to install on Windows 10 and 11, and use the README setup example as the main guide. Look up any current docs online if you need to.
