feat: AI enhancements on translate/customers/analytics pages

Translate: auto-detect source language toggle, one-click reply button that auto-fills inquiry and generates suggestions. Customers: AI suggested action column with smart heuristics based on status/health/last_contact. Analytics: AI-generated analysis summary showing key insights (customer count, top market, daily activity).
