chore: clean up codeflash JS workflow (#2499)

## Summary
- Normalize quote style to double quotes for YAML consistency
- Remove redundant `jest-junit` runtime install step (already in
devDependencies)
- Simplify codeflash CLI flags: `--all --verbose --yes` → `--yes`

## Test plan
- [ ] Verify workflow runs successfully on a test PR touching
`js/cf-api/` or `js/cf-webapp/`
- [ ] Confirm `npm ci` installs jest-junit from package-lock without the
extra install step
