/**
 * Filter inspectable ids by a query, matching the raw id OR its
 * human-readable name (the label drawn on the diagram), so an element can
 * be found by the name the operator sees — e.g. "LESQUIVE 400kV" — and not
 * only by its raw id. Shared by every inspect surface (the N / N-1 / action
 * tabs and the Remedial-action overview) so they stay in lock-step.
