This brings the new 'privacy mode' to use the standard widgets
and make the UX more smooth.
The swiping between pages / wallets is more visually satisfying.
We update the sync label to have a live counter of how long ago
the last block came in. (both front-ends)
A wallet can permanently be labeled a 'private wallet' which is a simple
boolean.
Then when you may need to hand over your phone to a clerk, all you do is
quickly enable the 'private mode' which is sufficiently deep in the menu
to make it hidden.
The effect is that all wallets marked private will be hidden for the
duration of that feature being on.
This moves the desktop account-details specific WalletSecretsView
component to live in the common area and we then use it from the backup
view for a wallet in mobile.
The only change is that we automatically detect if the content is too
wide to fit and we split it over 3 lines instead of 2.
This shows all wallets and wallet details.
Additionally, this moves the AccountTypeLabel out of the desktop page to
be reusable. Not so much because its hard, but because they have
translations and we'd better push shared translations into the common
translation unit as opposed to duplicating it.
The LabelWithClipboard now has as default context-menu-item text "Copy"
instead of "Copy Address".
