Background

The Gitea Actions runner and container registry are now live on jazz (see server-management#172). The ersatztv-ffmpeg base image is building successfully. The main ErsatzTV repo needs its own .gitea/workflows/docker-build.yml to build the app image.

Current State

The repo still has upstream .github/workflows/ (docker.yml, ci.yml, etc.) — these target Docker Hub/GHCR and multi-arch (amd64/arm32/arm64)
No .gitea/workflows/ directory exists yet
The Dockerfile at docker/Dockerfile references ghcr.io/ersatztv/ersatztv-ffmpeg:7.1.1 as base image — needs updating to 192.168.1.95:3000/timothy/ersatztv-ffmpeg:7.1.1

Tasks

Create .gitea/workflows/docker-build.yml — simplified amd64-only build targeting the Gitea registry
Update docker/Dockerfile to use 192.168.1.95:3000/timothy/ersatztv-ffmpeg:7.1.1 as base image
Configure buildx layer caching (cache-from/cache-to) — .NET restore + build are slow without cache
Set REGISTRY_USER and REGISTRY_PASSWORD secrets (already done)
Test a full build end-to-end and verify the image runs
The built image should be a test container — NOT replacing the production ghcr.io/ersatztv/ersatztv:latest that's currently running

Notes

The upstream docker.yml is a workflow_call (called from release.yml) with multi-arch matrix builds and manifest merging — we don't need any of that, just a simple amd64 build+push
Build args: INFO_VERSION (version string), BUILD_CONFIG (release)
Depends on the ffmpeg base image being available in the registry (ersatztv-ffmpeg#1 or equivalent)
