Make the DocuSeal fork relationship explicit in UI/email attribution

Render 'WaboSign, a fork of DocuSeal' (new fork_of i18n key) in the footer
and post-signing screen, add a fork credit to the email footer, and credit
WaboSign-as-fork-of-DocuSeal in completed.vue instead of crediting DocuSeal
alone. Also drop the orphaned unlock_with_docuseal_pro paywall i18n key (7
languages; no view or JS referenced it).
