test(11-01): add failing tender-query.builder spec (RED)

Extends TenderQueryDto with validated filter/sort params (q, openOnly,
deadlineFrom/To, valueMin/Max, includeNullValue, sort) and adds the
RED-first spec for the not-yet-implemented tender-query.builder.ts:
NULL-graceful value filter (D-05), openOnly deadline default (D-04),
explicit deadline range, and sort whitelist (UI-01).
