feat: Add uv Docker, Postgres, and company linking

Introduces uv-based Docker workflow with non-root runtime, cached installs, and uv-run for web and Celery. Updates docker-compose to Postgres + Redis, loads .env, and removes source bind mount for reproducible builds.

Switches settings to use Postgres when env is present with SQLite fallback; broadens allowed hosts for containerized development. Adds psycopg2-binary and updates sample env for Redis in Docker.

Adds company scoping to external data models and links sessions during ingestion; provides management commands to seed a Jumbo company/users and sync external chat data into the dashboard.

Includes .dockerignore, TypeScript config and typings, and minor template/docs tweaks.

Requires database migration.
