Initial commit : API Node.js + PostgreSQL + sync service Docker

- API Express/pg connectée à PostgreSQL (converti depuis mssql)
- 8 routes : articles, fournisseurs, commandes, stock, mouvements, performance, schema, sync
- Service sync nightly (mssql → pg, cron 3h00)
- Docker Compose : postgres + api + sync + frpc (tunnel sortant)
- Schéma PostgreSQL 17 tables dans postgres/init.sql
