fix(search): enable vector embeddings on context_memory_search_index (#28374)

Add the embedding fields (fingerprint, textToEmbed, chunkIndex,
chunkCount, parentId) to all locale variants of the context_memory
mapping and include dataAssetEmbeddings in its parentAliases.
Without fingerprint, OsUtils.addKnnVectorSettings() returned early
and never injected the knn_vector embedding field; without the
alias, vector search at /dataAssetEmbeddings/_search never fanned
out to the context memory index. Both gates are now satisfied so
ContextMemory participates in semantic search alongside tables,
glossary terms, and knowledge pages.
