feat(filesharing): only require email on sign step; name is optional

Remove the mandatory name disjunction from SIGN_ATTRIBUTES so senders
only need to prove their email address (the pre-#239 UX). The condiscon
infrastructure in postguard/pg-js remains available for future use.
Update locale strings to no longer mention the name requirement.
