stock: hide-kitlocker filter on list_components; fix supplier name in view_xref_sup_item

list_components defaults to hiding kitlocker components (KLID xref present) but keeps
those where the kitlocker contact is also the supplier (#SUP → SCREF='kitlocker') —
parts kitlocker supplies to elves. Filter checkbox in the search form, defaults on.

view_xref_sup_item: switch from xref_title (cross_ref_title = "Supplier") to linked_title
(liberty_content.title of the linked contact) so the contact name appears as the link text.
