feat(03-04): add custom admin columns for job moderation
Create DDHH_JM_Admin_UI class with custom columns for job_offer admin listing: - Anbieter (provider org name + contact person from user meta) - Standort (location from ACF field) - Art (job type from ACF field) - Eingereicht am (submission date) Removed default author/date columns to reduce clutter. Made columns sortable for efficient moderation workflow. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
