test(11-04): add failing test for TenderDetail component

Covers the three must-have truths: source link with safe target/rel, graceful NULL placeholders for value/deadline, and the mandatory no-local-mirroring notice for Vergabeunterlagen (rawPayload is 100% NULL in the live DB per research - no document URLs exist to mirror).

+/**
+ * TenderDetail.test — RED-first (TDD) proof for Plan 11-04 (UI-02, D-07).
+ * Mirrors the SourceConfigForm.test.tsx pattern: mock the api client
+ * module (getTender), render with a tenderId prop, assert via waitFor.
+ *
+ * Covers the three must-have truths from the plan:
+ * (a) a source link is rendered and points at the tender's sourceUrl
+ *     with a safe target/rel combination (T-11-09).
+ * (b) estimatedValue=null and deadlineAt=null render graceful German
+ *     placeholders instead of blank/error output (D-05 applies equally
+ *     to the detail view, not just the list).
+ * (c) the mandatory no-local-mirroring notice is always present — no
+ *     Vergabeunterlagen are fetched or mirrored locally (rawPayload is
+ *     100% NULL in the live DB; research finding, no document URLs
+ *     exist to mirror in the first place).
