feat(oci): run official container images as native LXC containers

Adds the OCI manager: an engine that turns a Docker Compose file into an
LXC definition, a catalog of 365 applications drawn from LinuxServer.io
and other container image sources, and a per-instance registry recording
what each container was built from. Reachable from the main menu.

Catalog text is translated like every other string in the project: the
taglines go through translate() and land in lang/*.json, so the entries
read in all eight languages instead of only English.

Translation cache builder:
- a failed translation leaves the key absent rather than writing English,
  which previously made the string count as translated forever
- a result identical to a 3+ word source is rejected, catching a provider
  that silently returns the text it was given
- strings that are nothing but glossary terms keep their source spelling
  instead of being discarded as failures
- no backoff between attempts when the provider is deterministic
- application names are protected so "HAOS One" survives translation
- argos joins the provider list, and the workflow reads the OCI sources

Audit & Report:
- findings that moved in the wrong direction between runs are reported
  alongside the ones that improved
- an accepted risk can carry a review date and is flagged when it falls due
- backup checks explain in plain language what they looked at and what to
  do next

Monitor:
- disks can be excluded from periodic reads, and an idle disk says so
  instead of showing a stale temperature
- per-disk identity survives a controller or enclosure change
- scheduled Borg backups resolve their SSH key from the repository entry
- PVE upgrades log the package list and the resulting dpkg changes

The web build no longer copies scripts/ into public/: the documentation
links to GitHub, so nothing read that folder.
