fix: rename check-permissions jobs to avoid workflow grouping issues (#22831)

The Formatter and Flow Validation workflows both had a job named
`check-permissions`, causing GitHub Actions UI to incorrectly group
jobs from different workflows together. This resulted in the test-results
job from Flow Validation appearing under the Formatter workflow section.

Renamed the jobs to be workflow-specific:
- formatter.yml: check-permissions -> check-permissions-formatter
- validation.yml: check-permissions -> check-permissions-validation

Updated all job dependencies accordingly to ensure proper workflow execution.
