feat(05-03): register 200x200px cropped image size for job logos

Add register_image_sizes() method to DDHH_JM_Post_Types class that
registers 'job-logo' image size (200x200px with hard crop). Hook
method to after_setup_theme action for proper WordPress timing.

This enables Elementor templates to request consistent logo sizing
via wp_get_attachment_image() using size 'job-logo'. Auto-generates
cropped version when logos uploaded via ACF field.
