The getSharedLink query sorts by updatedAt, but the sharedlinks
collection had no updatedAt index. Azure Cosmos DB for MongoDB
(RU-based) rejects sorts on non-indexed fields, causing an immediate
500 on GET /api/share/link/:conversationId whenever a conversation is
opened. Standard MongoDB is unaffected.
