Add coverage reporting/badges and split CI between Gitea and GitHub (#5)

Merge dotnet+jest coverage via reportgenerator, publish a self-hosted
coverage badge and build-status badges on the readme. Gitea remains the
full pipeline (build/test/docker push/deploy-qa/smoke); GitHub only
builds and tests since it has no registry secrets or qa runner.
