ui: Extract conversation import/export into ConversationTransferService The JSONL session format, ZIP archiving and browser downloads are pure I/O with no store state, so they move out of conversationsStore. The store keeps the DB orchestration (bulkExportConversations, downloadConversation, importConversationsData) and delegates the format work.
