chore(spec): hard-remove dead blank/record_review page config (enforce-or-remove) (#2268)

Completes framework#2265. Deletes BlankPageLayoutSchema/BlankPageLayoutItemSchema/
RecordReviewConfigSchema (+ inferred types), the blankLayout/recordReview fields on
PageSchema, and page-builder.zod.ts (the blank drag-drop canvas config) + its
studio re-exports — all unreachable (their page types have no renderer and were
removed from PageTypeSchema; objectui dropped refs in objectui#1949). page liveness
ledger → 15 props. Verified: spec UI 787 + studio 104 tests pass, typecheck clean,
liveness gate exit 0.

+chore(spec): hard-remove the dead `blank`/`record_review` page config (enforce-or-remove)
+
+Completes the enforce-or-remove started in framework#2265. The `blank` and
+`record_review` page types were already removed from `PageTypeSchema` (no
+renderer), their fields marked `@deprecated`, and objectui dropped all
+references (objectui#1949). This deletes the now-unreachable surface:
+
+- `BlankPageLayoutSchema`, `BlankPageLayoutItemSchema`, `RecordReviewConfigSchema`
+  (and their inferred types `BlankPageLayout`, `BlankPageLayoutItem`,
+  `RecordReviewConfig`).
+- The `blankLayout` and `recordReview` fields on `PageSchema`.
+- `page-builder.zod.ts` (the `blank`-type drag-drop canvas config:
+  `PageBuilderConfigSchema` / `CanvasSnapSettingsSchema` / `CanvasZoomSettingsSchema`
+  / `ElementPaletteItemSchema` / `InterfaceBuilderConfigSchema` and their types)
+  and its `@objectstack/spec/studio` re-exports — nothing consumed them.
+
+The `page` liveness ledger drops to 15 properties (the 2 `dead` entries are gone).
+No consumers in framework or objectui (objectui#1949 already merged).
