docs: Add multi-fix deployment verification to VERIFICATION MANDATE

- Extended verification checklist for sessions with multiple related fixes
- Added requirement to verify container newer than ALL commits
- Included example from Nov 16 session (3 fixes deployed together)
- Added bash commands for complete deployment verification
- Emphasized that ALL fixes must be deployed, not just latest commit
- Updated Common Pitfall #47 with deployment verification commands
- Prevents declaring fixes 'working' when only some are deployed

+**MULTI-FIX DEPLOYMENT VERIFICATION**
+When multiple related fixes are developed in same session:
+```bash
+# 1. Check container start time
+docker inspect trading-bot-v4 --format='{{.State.StartedAt}}'
+# Example: 2025-11-16T09:28:20.757451138Z
+
+# 2. Check all commit timestamps
+git log --oneline --format='%h %ai %s' -5
+# Example output:
+# b23dde0 2025-11-16 09:25:10 fix: Add needsVerification field
+# c607a66 2025-11-16 09:00:42 critical: Fix close verification
+# 673a493 2025-11-16 08:45:21 critical: Fix breakeven SL
+
+# 3. Verify container newer than ALL commits
+# Container 09:28:20 > Latest commit 09:25:10 ✅ ALL FIXES DEPLOYED
+
+# 4. Test-specific verification for each fix
+docker logs -f trading-bot-v4 | grep "expected log message from fix"
+```
+
+**DEPLOYMENT CHECKLIST FOR MULTI-FIX SESSIONS:**
+- [ ] All commits pushed to git
+- [ ] Container rebuilt successfully (no TypeScript errors)
+- [ ] Container restarted with `--force-recreate`
+- [ ] Container start time > ALL commit timestamps
+- [ ] Specific log messages from each fix observed (if testable)
+- [ ] Database state reflects changes (if applicable)
+
+**Example: Nov 16, 2025 Session (Breakeven SL + Close Verification)**
+- Fix 1: Breakeven SL (commit 673a493, 08:45:21)
+- Fix 2: Close verification (commit c607a66, 09:00:42)
+- Fix 3: TypeScript interface (commit b23dde0, 09:25:10)
+- Container restart: 09:28:20 ✅ All three fixes deployed
+- Verification: Log messages include "Using original entry price" and "Waiting 5s for Drift state"
