Pull the domain-agnostic combobox skeleton (pills region, search box, options
panel with its no-results node, outer container) into a private _combobox_shell
helper. SearchSelect now builds its form-specific pills and option rows and
delegates assembly to the shell. Rendered markup is byte-identical; a structural
test guards the fixed region order so future builders (e.g. a filter variant)
can share the shell without drift.
