fix(sidebar): remove mutation objects from useCallback deps

Mutation objects are not referentially stable in TanStack Query v5 — only
.mutate() and .mutateAsync() are stable. Removed deleteTaskMutation,
deleteTasksMutation, markTaskReadMutation, and markTaskUnreadMutation from
their respective useCallback dependency arrays to avoid unnecessary
recreations on every mutation state update.
