[feature] Automatically Fetch and Provide Carrier Invoices within Karrio #505

[danh91]

@MarcoWel

Is your feature request related to a problem? Please describe.
Carriers like UPS are not able to send their billing invoices by e-mail automatically. It requires manual login and invoice download.

Describe the solution you'd like
I want Karrio as a central hub for shipping providers to optionally fetch invoices from the carriers automatically and make them accessible in a central dashboard.

Describe alternatives you've considered
Manual file download.

Additional context
The challenge is that shipping providers like UPS and DHL do not expose an official API to grab billing documents.
We have developed a solution using chromedp that works fully automatic and should be quite straight-forward to integrate into Karrio.
