fix(gui): Force newline in discussion entries to prevent squashed layout

- Insert imgui.new_line() before rendering discussion content.
- Ensures the Markdown renderer inherits the full horizontal width of the panel.
- Definitively fixes vertical squashing of tables and long text blocks.

-- [ ] Task: Restore Monolithic Rendering
+- [~] Task: Restore Monolithic Rendering
     - [ ] WHERE: `src/gui_2.py`
     - [ ] WHAT: Move `render_discussion_entry` and related functions from `src/discussion_entry_renderer.py` back to `src/gui_2.py`.
     - [ ] HOW: Use `py_update_definition` for surgical insertion. Remove `src/discussion_entry_renderer.py` afterwards.
