[fix](ci) Change code-review workflow from approval-based to status-based tracking (#62469)

Replace GitHub PR review approval/request-changes mechanism with commit
status tracking for code-review workflow. The workflow now:
- Posts "pending" status on PR open/sync/reopen events
- Updates to "success" status when /review comment triggers automated
review
- Removes decision-based approval logic and RESULT_START/RESULT_END
parsing
- Changes gh pr review --approve to --comment for final summary
