Login refinements

**Is your feature request related to a problem? Please describe.**
The actual login needs a lot of double click actions and does not guide the login process.

**Describe the solution you'd like**
- login type (local/cloud) with two buttons instead of drop down menu
- direct drop down menu for selecting bin-file list instead of **use different file**
- **Load bin-file** button (instead of the entry in drop down menu - restore from backup)
- **Brainkey restore** button next to **Load bin-file**
- option to delete a file entry in the drop down list wallet list

**Screenshot**

No files, tests, or entry points are named. Start by locating the login screen and the existing local/cloud, bin-file, and Brainkey flows; completion means the requested login actions are directly available and wallet-list file entries can be deleted.
