web: skip task list re-render when dialog or panel is open

Prevents periodic poll from clearing the task panel, open modals,
or inline edit forms while the user is interacting with them.

- isUserEditing() now also detects any open <dialog> or task-panel
- poll() checks isUserEditing() before calling destructive renders
