feat(analytics): M2 self-improving chatbot analytics

Daily LLM classification of every chat (topics + product tags + deal
won/lost/undecided) aggregated into immutable daily metrics, with a
filterable admin report dashboard, product-catalog import (text/CSV/XLSX),
weekly persona summary, and an approval flow (LINE -> Telegram -> webhook)
for applying persona recommendations.

- Llm::AnalyticsClassifier: per-account openai -> Captain fallback cascade
- AccountDailyProcessor + Conversation/CustomerDailyMetric aggregation
- ReportService + DrilldownService (summary + deep filterable drilldown)
- AnalyticsReports.vue + productCatalog import UI (admin-only)
- WeeklyPersonaEvaluator + PersonaApprovalService (LINE/Telegram/webhook)
- Weekly cron (Mon 10:00) + daily cron (02:30)
