[30388f42] Infrastructure Hardening & Final Touches: Stabilized Lead Engine (Nginx routing, manager.py, Dockerfile fixes), restored known-good Nginx configs, and ensured all recent fixes are committed. System is ready for migration.

- Fixed Nginx proxy for /feedback/ and /lead/ routes. - Restored manager.py to use persistent SQLite DB and corrected test lead triggers. - Refined Dockerfile for lead-engine to ensure clean dependency installs. - Applied latest API configs (.env) to lead-engine and duckdns services. - Updated documentation (GEMINI.md, readme.md, RELOCATION.md, lead-engine/README.md) to reflect final state and lessons learned. - Committed all pending changes to main branch.
