[Feature] Expose serial data while flashing / bootup in a detail view

For debugging or users interested in details it might be useful to have the option to expand a "detail" pane during the install steps. The detail pane could show data received via serial from the connected device at that time.

This could help in error situations where a device can not be reset or shows errors during boot after the flash process.

I remember a similar thing when updating Ubuntu packages via UI here you can look at the console data in such a - initially hidden - detail pane.
