Added code so that in the backup seed phrase modal all actions can be performed with the enter key.
Also added logic for default focus on the confirm button in the ConfirmationDialog.
fixes#2359
There are some inconcistencies in the application when it comes to
button UI elements because we're using `StatusButton` in some places,
in other we use `StyledButton`. The latter is the original
component we've created when we started out building Status
Desktop, but is planned to be removed entirely in favour of
`StatusButton`.
This commit replaces the usages of `StyledButton` with `StatusButton`
Necessary cases are:
- Onboarding to show the list of 5 accounts
- In QML when we show it to the user for the backup
- Change it to a Loader, so the component and its memory is cleaned when closed
