feat(dealix): email HTML + language detection + config fixes — 40/40 tests pass

Module 1 — Email sender enhanced:
- HTML wrapper with Arabic RTL support
- List-Unsubscribe header for compliance
- send_email_batch() with configurable delays (2s between each)
- Gmail app password auth error message
- Plain text + HTML multipart
- Unsubscribe line auto-appended (ar/en)

Module 2 — Bilingual email generation:
- language field added to EmailGenerateRequest (ar/en)
- _detect_language() auto-detects from website domain
- _generate_email_en() produces full English email set
  (subject, body, 2 follow-ups, call script, LinkedIn msg)
- Arabic remains default for Saudi domains
- SECTOR_PAIN_MAP_EN for 4 key sectors

Module 3 — Config fixes:
- OLLAMA_BASE_URL + OLLAMA_MODEL (were referenced but missing)
- LLM_CACHE_ENABLED + LLM_CACHE_TTL
- GREEN_API_INSTANCE_ID + GREEN_API_TOKEN
- Outreach rate limits: WHATSAPP_DAILY_LIMIT=15,
  EMAIL_DAILY_LIMIT=50, EMAIL_BATCH_SIZE=10

All 40 tests pass (20 D0 + 6 fault + 14 automation).
