Add a Docker test harness for any Jellyfin version

test-image.sh publishes the plugin on the host, bakes it into a stock jellyfin/jellyfin image via Dockerfile.test, and runs it on :8096, with optional egress through a LAN gateway (DOCKER_GATEWAY, e.g. the Swiss VPN box) for geo-blocked streams. JELLYFIN_TAG (default 12) selects the image and the matching plugin build: 10.9/10.10 -> net8.0, 10.11 -> net9.0, 12 -> net10.0, with the generated meta.json targetAbi to match. Images are tagged per version (srfplay-test:<tag>) so several can coexist. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
