feat(quick-261016-nqk): ListExtendRecords and FormRecordTitle admin hooks (G-18.1-4)

pact.ListExtendRecords fills unstored fields of one list page before its
columns are read (WinterCMS listExtendRecords); such columns compile
unsortable and refuse sortable/searchable. pact.FormRecordTitle names a
record; the show, create and update responses send it as meta.title.
