refactor(utils): consolidate imports to fabric.utils

Removes unused `json` import and refactors imports to pull `GLib`, `Gtk`, `logger`, and `os` from `fabric.utils`, reducing module proliferation.

Details:
- Enhancements: Simplified import structure, removing redundant dependencies.
- Bug Fixes: None.
