ci: migrate to Portainer Git stack + registry-pushed image

- Compose: build → image (Gitea registry ci namespace); ./data → named volume pngx-data
- Workflow: build + push image + POST Portainer webhook (3-attempt retry on transient lease error)
- Drop transient .env file; secrets via Portainer stack Env
- Drop auto-version-bump commit-back (image SHA tag is the rollback handle)
- Add crowdsec@file to middlewares chain (defense-in-depth)

Repo secrets required: REGISTRY_TOKEN, PORTAINER_WEBHOOK_URL.
Rollback branch: pre-portainer-migration.
