ProxMenux 1.2.6.2-beta: OCI containers in the Monitor, docs and fixes

OCI manager Apps
- App tab: containers installed from an OCI image are identified from their
  installation record; the application and image versions are shown and an
  update is detected by image digest; repository link; Refresh data.
- Updates tab for OCI containers: Update and Recreate run the same flow as the
  OCI menu in the Monitor terminal; the pre-update backup can be kept in a
  backup storage; scheduled image updates with an optional minimum age.
- Logs tab: console output of the application, kept on the host
  (lxc.console.logfile + logrotate) and followed live.
- The Proxmox console opens a shell (cmode: shell) when the image has one.
- A damaged image download is fetched again before failing.
- Multi-container applications open at their LAN address; volume mount
  points on block storage report their usage.

Monitor
- Proxmox notifications are delivered to a loopback-only HTTP listener when
  HTTPS is enabled, so they no longer fail certificate verification.
- Log persistence counts recurring patterns only; an ended burst is not
  reported as persistent and its warning clears on its own (#386).
- Proxmox notification config backups are deduplicated and capped at three.
- The update icon on the Apps page opens the container on its Updates tab.
- Version 1.2.6.2-beta and its release notes in every Monitor language.

Docs
- OCI manager Apps and Audit & Report rebuilt as per-page message files,
  with a new page for OCI containers in the Monitor.
- Seven pages fixed where rich-text tags were missing from t.rich.

Translations
- Spanish fixes across the OCI engine, the Monitor and the TUI menus.
