feat(hosting): prospect search dropdown on site creation form

- Replace raw ID inputs with a live search dropdown that queries
  /admin/prospecting/prospects?search= as you type
- Shows matching prospects with business name, domain, and ID
- Clicking a prospect auto-fills business name, email, phone
- Selected prospect shown as badge with clear button
- Optional merchant ID field for existing merchants
- Remove stale "Create from Prospect" link on sites list (was just
  a link to the prospects page)
