feat(surveys): open surveys in a scrollable modal, fix page layouts

- list page and detail page use the standard site page wrapper (icon + title + subtitle)
- card click opens the survey in a scrollable shadcn Dialog; submitting removes the card on close
- detail page matches the helpdesk pattern: back link, title block, form in a card
- /surveys?open=<id> deep link auto-opens the modal; SurveyForm gained onSuccess
