fix(feedback): theme buttons, badge the Info button, simplify admin actions

- style the About feedback button and the form's Send/attach/remove buttons with
  the accent/border tokens used by the New Game CTA, so they follow light/dark
  theme (the previous .btn/.ghost classes were not defined globally); the attach
  button is a neutral 📎 icon button with an aria-label
- show a round badge on the About 'Feedback' button when a reply is waiting
- admin: one 'ban from feedback' checkbox shared by Delete and Delete-all (via
  button formaction); hide Mark read when already read and Archive when archived
- e2e: match the About button by substring (its name gains the badge)
