Consolidates duplicate KIS API client implementations (governance tests were exercising an unused class instead of the one actually running in production), closes a SQL injection path in the DB admin page, fixes a migration that used MySQL-only syntax and had never actually applied (confirmed against production), resyncs docs/db/quantengine.dbml with all migrations, and removes a duplicate OMS·WMS·ERP frontend tree in favor of src/frontend/. Also corrects several unverifiable/inflated claims in the OMS planning docs and realigns CI/CD and architecture documentation with what's actually in the repo.
