enh: Show confirmation dialog before submitting an empty form

[susnux]

• Resolves How to deal with empty responses #482

When submitting and empty form a confirmation dialog is shown, to make sure users submitted willingly an empty form.
Also please note the missing padding of the text in the dialog will be fixed with the next nextcloud-vue update (is a component bug not related to this PR).

Note: This can not be backported due to missing NcDialog in nextcloud-vue 7.

Was on vacation last week so only saw this now, some late design feedback @susnux :)

• There is very little outside padding, especially visible on the left of the content text and on the right and bottom of the buttons. Is this not handled by the component cc @marcoambrosini @szaimen ?
• We generally don’t use the wording "Abort" but instead "Cancel"
• The "Cancel" button does not need an icon as that calls for too much attention again despite being secondary :)

Indeed the confirm modal looks strange. @susnux any idea why?

As written in the initial post the padding is caused by a component bug fixed in nextcloud vue 8.3
