+Declare designer inputs for the `record:*` blocks (details, related_list,
+highlights, path) so they conform to the spec protocol (RecordDetailsProps /
+RecordRelatedListProps / RecordHighlightsProps / RecordPathProps in
+@objectstack/spec component.zod). They previously registered ZERO inputs — the
+visual designer could not configure them, and the spec↔frontend conformance
+check flagged 17 spec-only divergences. Now each block's inputs mirror its spec
+schema (columns/layout/sections/fields, etc.).
