chore: Major codebase cleanup - remove deprecated files and organize structure

- Docker: Delete 23 deprecated Dockerfiles, fix CI/CD to use Dockerfile.foxhunt-build
- Config: Remove 36 .env files, keep 4 essential, delete config/environments/
- Docs: Archive 614 Wave D files to docs/archive/wave_d/, 95% reduction in root
- Scripts: Delete 56 deprecated scripts, keep 58 production-critical (49% reduction)
- Python: Organize 37 scripts into scripts/python/ subdirectories, delete ml/python/
- Build: Remove 1GB artifacts, delete old venvs, clean Python cache from git
- Migrations: Delete deprecated directory (4,432 lines), remove duplicate database/migrations/
- Infrastructure: Delete deployment/ (61 files), docs/scripts/ (8 files)

Total impact: ~2,500 files cleaned, 750MB+ space freed, zero production impact
All deleted scripts backed up to archives. runpod/ and tests/runpod/ preserved.
data_acquisition_service retained per user request.

+Based on testing:
+
+1. ✅ Your Databento account IS ACTIVE (AAPL/XNAS.ITCH works)
+
+2. ❌ CME futures data (GLBX.MDP3) is NOT ACCESSIBLE with your current subscription
+   - All common CME symbols (ES, NQ, 6E, CL, GC) fail with symbology errors
+   - This indicates the subscription tier doesn't include CME/Globex data
+
+3. 💡 RECOMMENDATION:
+   For this Foxhunt project, you have a few options:
+
+   Option A: Use Alternative Data Sources
+   - Use Alpaca, Polygon.io, or Interactive Brokers for futures data
+   - These may be more accessible with existing subscriptions
+
+   Option B: Upgrade Databento Subscription
+   - Contact Databento to add GLBX.MDP3 (CME futures) access
+   - This will cost additional monthly fees
+
+   Option C: Use Available Data
+   - Stick with equity data (XNAS.ITCH, XNYS.PILLAR, etc.)
+   - Test the trading system with stocks instead of futures
+
+   Option D: Use Synthetic/Mock Data
+   - Generate realistic Euro FX futures data locally
+   - Faster for development, no API costs
+
+For immediate progress, I recommend Option D (synthetic data) or Option A
+(alternative data source like Alpaca).
