feat: self-hosted Docker image with Gitea Actions and Unraid docs

- Dockerfile: replace s6overlay with multi-stage build (golang:1.22-alpine
  builder + alpine:3.19 runtime), compiles from source, no goreleaser needed
- docker/entrypoint.sh: PUID/PGID support via su-exec
- .gitea/workflows/docker.yml: auto-build and push to Gitea container
  registry on every master commit (linux/amd64 + linux/arm64)
- README: add tmdb api_key docs, update Docker section to point to
  forge.dilain.com registry, add Unraid setup section
