perf(document-converters): offload sync embed_text/embed_texts to thread

Browse source 
generate_document_summary and create_document_chunks are async helpers
called from the chat path and from many connector indexers. Both wrapped
embed_text/embed_texts directly inside the coroutine, blocking the event
loop for the full duration of the embedding call.
