🐛 fix(i18n): localize container row tooltips, aria labels, and empty state

Wrap blocked-update tooltip (blockedTag/blockedTagWithCriticals/CVEs),
manual-update-only tooltip (manualUpdateOnly/WithMessage), four
aria-label attributes (ariaRegistryError, ariaSnoozedUpdates,
ariaSkippedUpdates, ariaMaturityBlocked), and empty state message in
ContainersGroupedViews.vue. Wire to existing keys where present; add
new keys for blocked/manual in en/zh-CN/zh-TW containerComponents.json.
