Improve the waiting for consent screen

[Tannybunny]

The waiting for consent screen doesn't look coherent with other screens and could use visual improvement.

Also, maybe it would be usefull for users to see the actual time that is left before the request expires. From the moving white bar it's a bit hard to tell.

Also at this stage it could be displayed who the lockees are ? So maybe if I really need to access immediately I could call the person. Maybe people will forget who they added as lockee for the vault. A similar thing is mentioned in #71 , although I wouldnt put avatar icons on the vault-screen, it will probably turn out messy
