feat: Add comprehensive database save protection system

INVESTIGATION RESULT: No database failure occurred - trade was saved correctly.
However, implemented 5-layer protection against future failures:

1. Persistent File Logger (lib/utils/persistent-logger.ts)
   - Survives container restarts
   - Logs to /app/logs/errors.log
   - Daily rotation, 30-day retention

2. Database Save Retry Logic (lib/database/trades.ts)
   - 3 retry attempts with exponential backoff (1s, 2s, 4s)
   - Immediate verification query after each create
   - Persistent logging of all attempts

3. Orphan Position Detection (lib/startup/init-position-manager.ts)
   - Runs on every container startup
   - Queries Drift for positions without database records
   - Creates retroactive Trade records
   - Sends Telegram alerts
   - Restores Position Manager monitoring

4. Critical Logging (app/api/trading/execute/route.ts)
   - Database failures logged with full trade details
   - Stack traces preserved for debugging

5. Infrastructure (logs directory + Docker volume)
   - Mounted at /home/icke/traderv4/logs
   - Configured in docker-compose.yml

Trade from Nov 21 00:40:14 CET:
- Found in database: cmi82qg590001tn079c3qpw4r
- SHORT SOL-PERP 33.69 → 34.67 SL
- P&L: -9.17
- Closed at 01:17:03 CET (37 minutes duration)
- No database failure occurred

Future Protection:
- Retry logic catches transient failures
- Verification prevents silent failures
- Orphan detection catches anything missed
- Persistent logs enable post-mortem analysis
- System now bulletproof for 16 → 00k journey
