Pad env rows and reflow the envs group

Give each env row its own horizontal padding so the key lines up with the
group's other content, and reflow the props and description literals in
env-row and envs-group.

 The app serves plain HTTP only; TLS is the reverse proxy's or tunnel's job, and the installer, the image's `HEALTHCHECK` and the dev server all assume it (`Bun.serve` gets no `tls`, there is no certificate handling anywhere). `isSecureRequest` still reads the proxy's `X-Forwarded-Proto`, so the auth and CSRF cookies get `Secure` and the installed app, Web Push and voice keep their secure context behind HTTPS; the installer binds `0.0.0.0` by default, and `--bind 127.0.0.1` limits it to a local proxy. Updates drop any `TLS_*` or `HTTP_REDIRECT_PORT` entries an older install left in `.env` and recreate a container that still mounts `/app/certs`.

 Images are built by GitHub Actions on a published release (`.github/workflows/release.yml`), for `linux/amd64` and `linux/arm64`, and pushed to both `ghcr.io/moduletrace/cobble` and `git.tben.me/moduletrace/cobble` with `latest`, version, `major.minor` and commit-sha tags. `.github/workflows/ci.yml` runs `bun run typecheck` and `bun run test` on every push and pull request, and checks that `install.sh` parses. The Dockerfile pins Bun 1.4.3 to match CI. The repository is mirrored on Gitea, and the installer defaults to the GHCR image with `--image git.tben.me/moduletrace/cobble` as the Gitea alternative.
