Subject: [PATCH] ci: migrate coverage badge from self-hosted SVG to Codecov

The coverage job previously generated a badge SVG and pushed it
directly to master/develop with a contents:write token. Now that
master requires PRs and disallows direct pushes, that push no
longer fits the branch protection policy.

Upload coverage to Codecov instead, which serves the badge itself
and needs no git push, letting the job run with contents:read.
