feat: stateless hot-reload Odoo 19 dev workspace for onebspace

- Dockerfile: verbatim upstream odoo/docker 19.0 + pip install requirements.txt
- easypanel.schema.json: source.type=dockerfile with inline Dockerfile
- deploy.py: calls Easypanel tRPC API directly (bypass MCP that only supports image)
- .gitea/workflows/build.yml: optional Gitea Actions CI
- README.md: full research + reproduction steps

+; Odoo 19 dev config — baked into the image. Overridable via bind mount.
+;
+; In dev: docker-compose mounts ./odoo.conf -> /etc/odoo/odoo.conf, so this
+; baked-in copy is shadowed. In CI / prod without a bind mount, this is the
+; config Odoo uses.
