Restart federation setup

[okjodom]

Add UX for restarting federation setup. These need design review as the UX spec doesn't include restart experience

Validations

• Lead guardian can initiate setup restart at SetConfiguration, ConnectGuardians, RunDKG or VerifyGuardians pages
• Any follower guardian can initiate setup restart at the same pages
• All guardians get notified of restart intent, and have to restart before proceeding

@Kodylow , @wbobeirne do test out this restart setup PR when you can. Did we have specific designs for restart UX?

[Kodylow]

The error message makes it seem like it's optional whether you should restart as well if there's another guardian who restarted. Like the restart isn't a "request" it's a "you are going to restart because another guardian restarted".
Should be more like "One of the guardians restarted the setup process".

Alternatively we could have it so only the setup leader can restart and then the message is "The Setup Leader Restarted the Ceremony". Think that would be better.

Then after I did a restart and tried again the followers all hung on this screen (shouldn't show restart here), until I refreshed. The setup leader stayed stuck here:

But all the followers would show this:

then be back on that 100% screen if you hit Approve again. And all the guardians would just stay hanging there.

@wbobeirne made some updates here with jodom:

Making it so only setup leader can initiate a restart. Then it has a confirm modal for are you sure you want to restart. Then folowers get notified the setup leader restarted the process and dump back to the first setup page.

Makes it way easier to avoid the whole setup leader vs folllower ordering bug. going to get some design feedback on it but after these changes and some testing it'll be good to go.

At @Kodylow's behest.
