[web] differentiate between password and wallet users in MissingCSATModal

Summary:
Depends on D11844

@ashoat and I realized earlier this week that we need to differentiate between wallet and password users when deciding what to display in the modal when a user is logged out.

came up with this copy for wallet users (to whom PAKE is not relevant)

Test Plan:
Wallet user:

Password user:

same test plan as in prior diffs but with wallet and password users, to ensure both modals are displayed correctly. see above images
