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

.gitea/workflows/build.yml

+# stateless-container-for-onebspace-development — Gitea Actions workflow
+#
+# Builds the os-dev image on every push to 1b-agent/os-dev's 19.0 branch and
+# pushes to the local Gitea Container Registry. Same syntax as GitHub Actions;
+# Gitea Actions is API-compatible.
+#
+# Tags produced:
+#   agents-apps-and-tools-gitea.nxldoy.easypanel.host/1b-agent/os-dev:19.0
+#
+# The registry lives at the non-git hostname (where the Let\'s Encrypt cert
+# matches *.nxldoy.easypanel.host). The git.* hostname is for the git/web UI.
+#
+# NOTE: This workflow is OPTIONAL for the Easypanel source.type=dockerfile
+# approach (Easypanel builds the image in-place). It\'s useful if you also
+# want a Gitea Container Registry copy for other consumers.
