fix(auth): the sign-up notice links the privacy statement, with a space

The link under the Register button was glued to the sentence before it: htm
drops whitespace that holds a line break, so "deleted.Legal information".
It also pointed at the hub's /legal/ index. Where an account is created is
where GDPR art. 13 owes the person the information about their data, so it
now links the privacy statement itself — /legal/confidentialite.fr.txt in
French, /legal/privacy-statement.en.txt in every other language — on the
hub that served the page, like every legal link. The sidebar's "Legal
information" is unchanged.

Checked in Chrome and Firefox (headless), in English and French.
