feat(04-01): add deactivate action to provider dashboard

Add deactivate mode detection alongside existing edit mode checking for action=deactivate_job and job_id parameter. When in deactivate mode, render deactivation form section similar to edit section structure with heading "Stellenangebot deaktivieren", back link to dashboard, and form shortcode with id_param={job_id}. In job listings table, add "Deaktivieren" button in Actions column only for published jobs (status === 'publish'). Deactivate button uses warning/destructive color (red background) to differentiate from edit/view buttons. Follow same conditional rendering pattern as edit mode showing deactivation form OR listings, not both.
