fix(gui): use imscope.child for comms_scroll (was inside conditional, leaving child open)

ROOT CAUSE: render_comms_history_panel had imgui.end_child() nested INSIDE
an 'if app._scroll_comms_to_bottom:' block at line 3758. When
_scroll_comms_to_bottom was False (the common case), end_child was
NOT called, leaving the comms_scroll child window open. This caused
the imGui state to corrupt: tab_item.end_tab_item, tab_bar.end_tab_bar,
and the outer window.end all saw that the child was still open
(WithinEndChildID was set), triggering 'Must call EndChild() and not
End()!' assertion.

FIX: Convert the entire comms_scroll block to imscope.child (which uses
Python's with statement for exception-safe end_child). The scroll-to-bottom
logic is now correctly nested INSIDE the with block, and there's no
manual end_child to forget.

Tests:
- Updated test_comms_scroll_no_clipping.py to check imscope.child
  instead of begin_child
- 28/28 broad regression pass
