Improving compatibility with WPML

### Is your feature request related to a problem? Please describe
When deleting a Job post or Resume post from the frontend (Job Dashboard), their translations are not automatically deleted. This occurs because WPML restricts the `delete_post` action to REST requests.

### Describe the solution you'd like
**For jobs**
- Open /wp-content/plugins/wp-job-manager/includes/class-job-dashboard-shortcode.php
- Look for line 466
- Replace:
```
case 'delete':
// Trash it.
wp_trash_post( $job_id );
```
- With:
```
case 'delete':
// Trash it.
// WPML workaround for compsupp-7729
if ( class_exists('Sitepress') ) {
$trid = apply_filters( 'wpml_element_trid', NULL, $job_id , 'post_job_listing' );
$translations = apply_filters( 'wpml_get_element_translations', NULL, $trid, 'job_listing' );
if ( !empty( $translations ) ) {
foreach ( $translations as $lang => $translation ) {
$translation_id = absint( $translation->element_id );
wp_trash_post( $translation_id );
}
}
} else {
wp_trash_post( $job_id );
}
```
**Same thing for Resumes**
- Open /wp-content/plugins/wp-job-manager-resumes/includes/class-wp-resume-manager-shortcodes.php
- Look for line 125
- Replace:
```
case 'delete':
// Trash it.
wp_trash_post( $resume_id );
```
- With:
```
case 'delete':
// Trash it.
// WPML workaround for compsupp-7757
if ( class_exists('Sitepress') ) {
$trid = apply_filters( 'wpml_element_trid', NULL, $resume_id , 'post_resume' );
$translations = apply_filters( 'wpml_get_element_translations', NULL, $trid, 'resume' );
if ( !empty( $translations ) ) {
foreach ( $translations as $lang => $translation ) {
$translation_id = absint( $translation->element_id );
wp_trash_post( $translation_id );
}
}
} else {
wp_trash_post( $resume_id );
}
```

Start at the delete cases in includes/class-job-dashboard-shortcode.php around line 466 and wp-job-manager-resumes/includes/class-wp-resume-manager-shortcodes.php around line 125. Review the existing frontend deletion flow and WPML hooks shown in the issue; done means deleting a job or resume also trashes its translations when WPML is present, while preserving deletion without it.
