feat: фаза 3 — i18n RU/EN, /metrics, AI disclaimer, initiator+IP, LLM очередь

3.3 i18n: модуль с RU/EN словарями, LangMiddleware (cookie+query),
     Jinja-фильтр t(), переключатель EN/RU в nav, перевод ключевых
     строк интерфейса
3.5 /metrics: Prometheus-совместимый endpoint (scans_total,
     scans_flagged, findings_total, by_status, by_ecosystem,
     last_scan_timestamp)
3.2 AI disclaimer: сноска под каждым LLM-вердиктом (.llm-disclaimer)
3.4 LLM очередь: asyncio.Semaphore(LLM_MAX_CONCURRENT_ANALYSES)
3.1 initiator + source_ip: поля в Scan, захват из webhook payload,
     показ в scan_detail + API
3.6 UI: убран stat-minibar и heatmap с дашборда
