fix(sync): refresh sidebar session list after pull completes or data deleted

After a sync finishes (triggerPull/triggerPullAll/onPullResult), reload the
session list so newly imported chats appear in the sidebar immediately.
Also refresh after removing a subscription with deleteData=true so the
deleted session disappears from the sidebar.
