Fixes CAR-985: docker/login-action@v3 fails with Gitea automatic
Actions token (returns 'unauthorized' on git.farh.net/v2/).
Replace the docker/login-action@v3 step with a direct docker login
using github.token piped via stdin. The github.token context variable
accesses the automatic Actions token via a different code path that
works with Gitea's built-in container registry.
Changes:
- .github/workflows/build-dev.yml: replace docker/login-action with
direct 'echo github.token | docker login'
- .github/workflows/build-prod.yml: same replacement
- .gitea/workflows/build-dev.yml: same replacement
- .gitea/workflows/build-prod.yml: same replacement
