fix: silent fetch POST instead of new-window form, update subtitle

- Replace hidden form POST (target='_blank') with silent fetch() that
  ignores the response — no new window opens
- Send boolean values directly instead of serializing to 'true'/'false' strings
- Update subtitle: 'Download your PDF in minutes.' -> 'We will send the report in minutes.'
