Align patient info population between design and dev

[fzhao99]

Designs for the patient info (step 1) page are misaligned with dev. This ticket captures the work to align them, which includes

• Replacing the patient dropdown selection with a "golden" fake patient that has all the information across all use cases (#2645). Adding this patient makes the patient dropdown and query use case dropdown obsolete and can then be removed.
• We can only do this after the select patient / query pages are built / available so to not break the demo experience on main. Plan is to put those pages in first without any redirection and then wire everything together to keep the PR's small.
  • This might be a good opportunity to revisit whether our SPA setup is still serving us, or if want to start building out some sort of URL scheme to allow deep linking into separate steps of the query flow
• If we need to break this ticket into a redirection / routing step and a design pass step, we can do that once we know more of what the work looks like.
