Update claude-easy-fixes workflow to use phpstan-bot and peter-evans PR action

- Use PHPSTAN_BOT_TOKEN for checkout and GH CLI (matching update-phpstorm-stubs.yml)
- Configure git committer as phpstan-bot instead of github-actions[bot]
- Replace Claude-driven PR creation with peter-evans/create-pull-request@v6
- Add explicit setup-node step with npm cache
- Remove --max-turns CLI option
