feat(03-02): integrate edit form into provider dashboard

- Add edit mode detection via URL parameters (action=edit_job&job_id=X)
- Display edit form when in edit mode, hide listings table
- Update edit links in table to point to dashboard edit form
- Add back navigation link to return to dashboard overview
- Style edit section with card layout and back link
- Form pre-populates with existing job data via id_param
- Dashboard shows either edit form OR listings, not both
