v3.31.0

Added

• Sentinel notifications now speak your Home Assistant language. The fixed parts of every Sentinel notification — the title (Security Alert / Home Alert / Home Update), the subtitle, finding-type labels, the burst-batch summary, the daily digest, and the permanent-snooze confirmation prompt — now follow the Home Assistant server language (Settings → System → General), currently in English and Czech with automatic fallback to English. This is independent of the sentinel_response_language option, which only affects the LLM-written explanation text. The deterministic security message bodies deliberately stay English: they quote exact cameras, entries, and times that a translation could blur. Contributed by @hruba202 (#565).

Fixed

• Notification delivery can no longer be broken by unexpected stored data. The daily digest now tolerates malformed audit records and findings with a missing severity, and a bad placeholder in any localized string degrades gracefully to the English text instead of raising on the alert path.
