fix(i18n): protect the literals a reader copies, and name the OCI category

The glossary only holds what someone listed, and what reaches the reader
as a broken command was never on it. Paths, long options and Proxmox
subcommands are now recognised by shape:

    /dev/apex_0        came back as  /dev/apex 0
    --auto-uninstall                 desinstalación automática
    pct config 110                   configuration PCT 110   (fr)
    pct enter 101                    pct inserire 101        (it)

OCI joins the glossary as well. Read as a word it became "BEC" in French
across thirty-one strings — "Vérification du BEC" named nothing — and the
menu entry read "Gestionnaire du BEC Apps". The entry itself and "beta"
are protected too, so the name stays the same in every language.

A provider can also alter a token rather than carry it through: argos
returned MPXTERM000 for PMXTERM000, the restore found nothing, and the
token shipped. "MPXTERM000 configuré" is in the French catalogue today.
The restore now verifies its own tokens and fails the string instead,
which leaves the key absent for the next run to retry.

Spanish category labels: twenty-six were wrong. Seven collapsed two
categories into one — "Backup & Recovery" read only "Recuperación",
"Network & Firewall" read "Red de cortafuegos" — six were half
translated, and the connector alternated between "&", "y" and "e". They
now use "y" or "e" throughout. "IoT & Smart Home" and
"AI / Coding & Dev-Tools" stay in English by choice.

"Messaging & Queues" becomes "Messaging & Notifications": its only
application is Apprise, a notification gateway, not a queue. The
Helper-Scripts import still maps their name, so nothing breaks upstream.
