Feat/typeorm

[marrouchi]

Motivation

This PR replaces Mongoose/MongoDB with TypeORM across the API. Why? To make local development frictionless, enforce relational integrity, and unlock native Postgres features such as pgvector for RAG-style embedding search.

Key advantages

✅ Run locally with SQLite — no Docker required for dev

✅ Postgres + pgvector ready for production semantic search

✅ Real foreign keys & constraints (fewer orphaned records)

✅ First-class transactions and migrations

✅ DB-agnostic (SQLite for dev/tests; Postgres/MySQL for staging/prod

Installation :
