Refactor Discord member statistics handling and remove unused components

- Removed the `guild_member_stats` table and related logic from the database and models, as well as the associated webapp routes and templates.
- Cleaned up the Discord bot initialization by eliminating unused imports and functions related to member statistics.
- Updated logging configuration in `run-web.py` to streamline the startup process and improve thread management.
