Bug: Router SAMBA network drive doesn't show username and password prompt

### What feature or improvement do you think would benefit Files?

At present, Files detects I have a drive attached to my router accessible as a shared drive. If I click on it, I get the error that "guest login" is blocked. This is expected.

A username and password is required but there is no apparent option to enter that information. It would be good if I could do this from files or be directed to the proper location in Windows to enter that information.

Running Win 11 25H2 locally.

### Requirements

Allow access to secure SMB connections

### Files Version

4.0.11.0

### Windows Version

11.26200.7019

### Comments

_No response_

Start by reproducing the shared-drive behavior in Files 4.0.11.0 on Windows 11 when guest login is blocked, then trace how Files handles the SMB connection. Done means a user can provide credentials for the secure connection in Files or is directed to the proper Windows location to enter them.
