Replace the Node/Express backend with a Rust implementation that keeps
the same REST API, MongoDB collections and Redis cache keys, so existing
users, subscriptions and progress keep working.
- axum + mongodb + redis, bcrypt and HS256 JWT compatible with old data
- RSS parsing, iTunes discovery/trending, background sync (1h / 4h)
- Docker image now builds a static Rust binary on debian-slim
- CI runs cargo tests before publishing the image
- compose uses pull_policy: always so a restart picks up the new image

- Add .github/workflows/docker-publish.yml: builds Docker image on every
push to main and publishes to ghcr.io/r0m1k3/podcastic:latest automatically
- docker-compose.yml: replace local `build:` with `image: ghcr.io/r0m1k3/podcastic:latest`
so Unraid's "Update" button can pull the image directly from the registry
instead of failing with "no service selected"
- Remove deprecated `version: '3.8'` field
