Issue:
Include restore via backup file using Liana Connect in the add an existing Liana wallet flow
A user can currently just enter the descriptor, we should let them have the possibility to upload a backup file:

![Image](https://github.com/user-attachments/assets/2eb61fc1-740e-4225-b2c7-f93d4eeb74aa)

The section should become:
```

**Load a wallet from backup file / descriptor**
Upload the wallet backup file or paste its descriptor to add it

"Import descriptor" button

or

"Descriptor"
(paste area)
```

This work is important since we won't have the backend switch in the settings but we will indicate the user how to restore easily the wallet with a new backend/node option. Using the file is much simpler, easy to understand and we should standardize it for all backend options.

Pull request description:
Add an option for add a descriptor from file/backup for liana-connect
This PR closes #1751:
 - add the option to import a descriptor from a file.
 - add a spacer at the bottom of the screen.
 - add the possibility to import also a descriptor from a backup file.
