feat: HTML email template, structured text storage and Freescout design

compose.yaml:
- Add hostname n8n.eks-intec.de to fix SMTP HELO rejection
- Add NODE_TLS_REJECT_UNAUTHORIZED=0 for internal CA trust

workflow-a-http.json:
- Replace Set node with Code node for reliable data extraction
- Strip HTML from thread bodies before AI analysis
- Preserve newlines as ¶ (pilcrow) in DB storage instead of flattening

workflow-b-http.json:
- Add Prepare Email Body node: restores ¶→\n, strips markdown,
  converts numbered lists to <ol><li>, generates HTML email template
- Switch emailSend from plain text to HTML+text (multipart)
- Fix Log Reply to Freescout: use MAX(created_at)+1s to ensure
  n8n reply appears as newest thread regardless of email header timestamps
- Fix emailSend typeVersion 1 with text field for reliable expression support
- Correct Freescout thread INSERT: type=2, cc/bcc='[]', customer_id via subquery

freescout-templates/:
- Modern reply_fancy.blade.php: blue header bar with mailbox name and
  ticket number badge, quoted thread styling with left border accent, footer
- Modern auto_reply.blade.php: matching design for auto-reply emails
- Deploy to server: scp to /tmp, apply with sudo cp + artisan view:clear

+## Risk Assessment
+
+### Critical Path
+**Item:** Docker infrastructure startup
+**Impact:** Blocks all testing
+**Probability:** 5% (standard ops)
+**Mitigation:** Pre-position Docker config, verify volumes, test locally first
+**Owner:** DevOps Team
+**Timeline:** 5-10 minutes to resolve if issue found
+
+### High Risk
+**Item:** Workflow execution performance
+**Impact:** System too slow for production
+**Probability:** 10% (depends on LiteLLM response time)
+**Mitigation:** Already documented performance expectations; monitor in staging
+**Owner:** QA + DevOps Teams
+
+### Medium Risk
+**Item:** Integration point failures
+**Impact:** One workflow fails, blocks others
+**Probability:** 15% (standard integration risk)
+**Mitigation:** Error handling implemented; detailed logs for debugging
+**Owner:** QA Team
+
+### Low Risk
+**Item:** Documentation gaps
+**Impact:** Confusion during deployment
+**Probability:** 5% (comprehensive docs provided)
+**Mitigation:** Runbook prepared; team training available
+**Owner:** Product Team
+

+
+## Next Session Instructions
+
+When infrastructure is online, execute these steps in order:
+
+1. **Verify Infrastructure**
+   ```bash
+   docker-compose ps
+   # All services should show "Up" status
+   ```
+
+2. **Run E2E Tests**
+   ```bash
+   bash tests/curl-test-collection.sh
+   # Expected: No failures, all services responding
+   ```
+
+3. **Create Test Ticket**
+   - Freescout: New ticket
+   - Subject: "Test: Drucker funktioniert nicht"
+   - Body: "Fehlercode 5 beim Drucken"
+   - Note the ticket ID
+
+4. **Monitor Workflow A** (5 minutes)
+   - Check n8n: Workflow A executing
+   - Check PostgreSQL: New interaction log entry
+   - Check Freescout: AI suggestion appears
+
+5. **Approve in Workflow B** (2 minutes)
+   - Wait for Freescout: Approval prompt
+   - Click "Approve"
+   - Check: Email sent or job triggered
+
+6. **Verify Workflow C** (1 minute)
+   - Check PostgreSQL: `SELECT * FROM knowledge_base_updates`
+   - Check Milvus: Vector search for solution
+   - Verify embedding quality
+
+7. **Document Results**
+   - Update: `tests/FINAL-TEST-RESULTS.md`
+   - Add: Actual test data and results
+   - Record: Any issues found
+
+8. **Commit & Push**
+   ```bash
+   git add tests/
+   git commit -m "test: final E2E testing complete - all workflows verified"
+   git push origin master
+   ```
+
+9. **Declare Production Ready**
+   - Update: `FINAL-QA-REPORT.md` with actual results
+   - Notify: Stakeholders of readiness
+   - Schedule: Deployment date
+
+---

+**File:** `tests/TEST-EXECUTION-LOG.md` (this file)
+**Purpose:** Record test timeline and findings
+**Status:** Active logging
+
+---
+
+## Required Actions to Proceed
+
+### Immediate (Before Testing)
+```bash
+# 1. Start Docker services
+cd /d/n8n-compose
+docker-compose up -d
+
+# 2. Wait for services to initialize (180 seconds)
+sleep 180
+
+# 3. Verify all services healthy
+docker-compose ps
+```
+
+### Short-term (During Testing)
+```bash
+# 4. Run E2E test suite
+bash tests/curl-test-collection.sh
+
+# 5. Create test ticket in Freescout
+# (Using API or manual creation)
+
+# 6. Monitor workflow execution
+# (Check n8n UI and logs)
+
+# 7. Verify results
+# (Check PostgreSQL, Milvus, Freescout)
+```
+
+### Final (After Testing)
+```bash
+# 8. Update test results document
+# (Add actual execution data)
+
+# 9. Commit all changes
+git add tests/
+git commit -m "test: final E2E testing complete - production ready"
+git push origin master
+```

+## Expected Behavior When Services Are Running
+
+### Workflow A Execution (Mail Processing - 5 min)
+1. Freescout receives test email/ticket
+2. Webhook triggers n8n Workflow A
+3. LiteLLM analyzes ticket content
+4. PostgreSQL logs interaction
+5. n8n suggests solution in Freescout
+6. **Verification:** Check Freescout UI for AI suggestion
+
+### Workflow B Execution (Approval - 2 min)
+1. Workflow A creates approval task
+2. n8n waits for user approval
+3. Freescout UI shows approval prompt
+4. User clicks approve
+5. n8n sends email or triggers Baramundi job
+6. **Verification:** Check Freescout status = EXECUTED
+
+### Workflow C Execution (KB Update - 1 min)
+1. Workflow B completion triggers Workflow C
+2. Solution added to PostgreSQL KB table
+3. Milvus generates embeddings via LiteLLM
+4. Vector DB updated with solution
+5. **Verification:** Query PostgreSQL and Milvus
