Add FilaCheck to larasets PHP workflow stubs

[Copilot]

Larasets’ PHP workflow stubs now include FilaCheck alongside the existing PHP checks, so Filament-specific issues are covered in both PR validation and auto-fix flows.

• PR validation

  • Adds tomgrv/actions/run-filacheck@v1 to validate-pr-php.yml
  • Runs against app/Filament and only when the project includes Filament

• Auto-fix workflow

  • Adds a FilaCheck fix step to fix-php.yml
  • Expands PR generation conditions to include FilaCheck output
  • Keeps generated fix PRs aligned with all fix-capable PHP checks
  • Only runs the FilaCheck fix step when app/Filament exists

Example:

- name: Run FilaCheck
  uses: tomgrv/actions/run-filacheck@v1
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    path: app/Filament

[tomgrv]

Should run only if filament-enabled project.

[Copilot]

Should run only if filament-enabled project.

Done in f20a876: FilaCheck now only runs when app/Filament exists, so it stays scoped to Filament-enabled projects.
