Store UI language per user (users.language column, migration 26).
Language selector moves from Panel tab to Profile tab — each account
picks its own language, saved to DB and applied via i18n.changeLanguage()
on save so the interface switches immediately.
Panel tab: panel_name read-only (falls back to env PANEL_NAME),
log_retention_days field exposed in UI, language selector removed.
Panel API accepts panel_name in PUT so it can be overridden in DB
without touching the env var.

Add target node and storage overrides to single and bulk restore flows, and
track Proxmox task progress (parse_task_progress in the monitoring worker,
new ProxmoxTask progress column + migration, enriched task API responses).
