Config Refactor: unify config handling

- Consolidated all system/user config logic into configmanager.py
- Removed duplicate loaders from setup.py and TUI.py
- Eliminated .env redundancy; now only stores WORKING_DIR
- Clarified boundaries: system config immutable, user config mutable
- Updated TUI to use save_user_config()
- Removed all deprecated/legacy config functions and aliases
