Very large documents cannot be uploaded

I have a very large 130 MB PDF file that I would like to place into Docspell, but I have been unsuccessful in uploading it. In all cases, timeouts kill the upload before it has time to complete. This is even the case when using `dsc` from the same server running Docspell. I feel like the timeouts should probably be relaxed here.

> Cmd: Watch: Uploading failed: An http error occurred: An error was received from http://docspell-restserver:7880/api/v1/open/integration/item/xxx: error sending request for url (http://docspell-restserver:7880/api/v1/open/integration/item/xxx): operation timed out

If it is important, I'm still using the default Postgres storage backend. I can't find anything in the documentation that would recommend against using the database backend for these large files, but if that is the case then I'd appreciate any guidance!
