docs(backlog): WP-11 + WP-12 done; note WP-13 upload correction

The CIBG UI fidelity pass completed WP-11 (aanvragen/application-link) and WP-12
(Datablock), and reworked the upload suite to wrap vendored CIBG classes rather
than mark it as a gap (WP-13's assumption corrected).

 Status: todo
 Phase: 2 — CIBG fidelity
 
+> **Correction (CIBG UI fidelity pass, b5c5d30):** this WP assumed the `upload/` suite
+> had no vendored CIBG classes and would be marked as a CIBG-gap ("Bestand-upload").
+> The vendored build actually ships a full upload vocabulary (`.file-picker-drop-area`,
+> `ul.file-list`, `.file-container`, `.file-name`/`.file-meta`, `.btn-upload`,
+> `.upload-validation`), so the suite was **reworked to wrap those classes** instead —
+> it is no longer a gap to mark. WP-13's remaining register still covers skeleton/
+> spinner, rich-text-editor, wizard-shell, confirmation, card (`.app-card`),
+> status-badge, placeholder-chip, etc. (Note: `application-link`'s non-navigating
+> `.static-row` mirrors the aanvragen card surface from tokens — a small marked-gap
+> candidate.)

 ## Why
