Partition metadata cache entries by namespace mode.

getMetadata now stores the new mode before reading an ID-only cache entry. A sidebar mode switch can therefore send previous-mode metadata to the sidebar callback, while later template and update URL helpers resolve that metadata with the new mode. This creates an incorrect intermediate sidebar state and can produce mode-inconsistent update requests.

Include metadataNamespaceMode in the cache key so each mode reads and writes its own metadata.

Suggested fix 
-    getMetadataCacheKey(id: string): string {
-        return `${CACHE_PREFIX_METADATA}${id}`;
+    getMetadataCacheKey(id: string, metadataNamespaceMode: string = this.metadataNamespaceMode): string {
+        return `${CACHE_PREFIX_METADATA}${id}:${metadataNamespaceMode}`;
     }
 
     ...
 
         const cache: APICache = this.getCache();
-        const key = this.getMetadataCacheKey(id);
 
         // Per-call mode for this fetch; persist on the instance so later
         // URL helpers on this client match. APIFactory copies it onto the
         // next Metadata client, which would otherwise default to SCOPED.
         const metadataNamespaceMode = options.metadataNamespaceMode || this.metadataNamespaceMode;
         this.metadataNamespaceMode = metadataNamespaceMode;
+        const key = this.getMetadataCacheKey(id, metadataNamespaceMode);

Review comment at @src/api/Metadata.js around lines 1060 - 1065:
Update getMetadataCacheKey to include metadataNamespaceMode in each cache key,
with the current instance mode as its default. In getMetadata, resolve the
effective mode from options before building the key, then use that mode-specific
key for cache reads and writes so metadata from different modes remains
separate.
