fix(gui): Resolve Markdown squashing, MiniMax compression error, and UI import issues

- Modularize discussion entry rendering to src/discussion_entry_renderer.py to fix layout squashing.
- Fix MiniMax compression routing with robust case-insensitive check and synced base URL.
- Implement src/ui_shared.py to resolve circular imports and consolidate shared UI helpers.
- Finalize Structural File Editor integration and state unification.
