Improve CI: readable job names, codec matrix for all jobs, fix duplicate runs

- Use matrix include with named codec variants (postcard/pot) for
  readable job names instead of raw cargo flags
- Add codec matrix to integration tests via npm scripts (test:pot)
- Set workspace dep to default-features = false so test crate can
  switch codecs independently
- Only trigger on push to main + all PRs (avoids duplicate runs)
