fix(i18n): repair strings the translator damaged in the TUI catalogue

Three faults, all user-visible in the released catalogue.

The context prompt survived into 13 translations. A reader of the
Italian TUI was told "Messaggio tecnico per Proxmox e IT.Traduzione:
impossibile aggiornare initramfs." — the instruction given to the
provider, printed as if it were the message. One in French, eight in
Italian, four in Portuguese. The text after the prefix is correct, so
only the prefix goes.

Fifteen strings carried HTML entities where the source had a plain
character: "Adblock " DNS", "Affari & ERP".

Three product names had been translated as words — "Vaultwarden Courbe
Web" in French, where courbe means curve — and now keep their published
spelling. Two German strings said Kunden, a commercial customer, for an
OAuth client. Existing translations of the category labels and the
descriptive taglines are left as they are.

Twelve strings had no value in some locale and were retried on every
run, about thirty-five minutes a time. A fresh extraction now reports
nothing pending in any of the seven.

The Monitor catalogues are clean: they send no context prompt.
