FR: Show invite creation date and accept date in "Share" menu, notify via email

### What are you trying to do?

For a security review feature, it'd be really nice to better track invitations sent to a machine. First, one should get an email notifying which account accepted an invite created when.

Then, in the "share" pop-up, it would be nice to show, for existing invites, when were they created, and when were they accepted. This way, it'd make it easy to understand who they belong to, since email is not always informative enough.
