perf: remove duplicate tasks query

Removed redundant useTaskSearch call from ChatView since HistoryPreview
already makes its own call to fetch the tasks it needs to display.

This eliminates an unnecessary API call on application startup and
simplifies the component by removing conditional rendering based on task count.
