fix(gui): Resolve MiniMax compression error and fix Markdown table rendering

- Correctly route 'minimax' provider in run_discussion_compression.
- Fix MiniMax base URL to api.minimax.io to match main sender.
- Refactor read-mode discussion entries to always use a scrollable child with auto-resize.
- Remove redundant text wrapping that caused Markdown tables to squash vertically.
- Clean up duplicate separators in discussion hub.
