Implement Copy/Print/Save as File actions under "Backup your wallet"

[NejcZdovc]

Implement copy, print and save as File in Backup/Restore dialog.

maybe we could move this to 1.0 considering a user can copy and paste the codes using cmd+c or the right click menu.

agree

Could we hide the nonfunctional buttons in the meantime? I just encountered this and was briefly perplexed. Might frustrate/unnerve some end users.

Also, might consider adding some copy saying "you can select and copy the recovery key with the Cmd-C copy keyboard shortcut." I figured that out via trial and error but it's not exactly obvious.

@NejcZdovc the implemented design is different from the original spec screenshot mentioned in the issue? Can you confirm which one is to be verified?

[NejcZdovc]

@srirambv yes we changed design, what you have on the screenshoot is correct (except duplicated text)
