UX Refactor: Pauses, Status & WiFi

- Implemented global `_pause()` logic across all modules (`utils`, `gaming`, `firmware`, etc.), replacing hardcoded `read -p` calls to standardize exit pauses.
- Unified MangoHud installation into a single command (`apt install -y mangohud:i386`) for gaming and legacy branches.
- Refactored `_inst()` to return `*` instead of `(installed)`, moving the function globally to `utils.sh` and removing duplicates from helpers.
- Enhanced Broadcom WiFi detection with expanded grep patterns ('network controller', 'wireless', etc.) and ID fallback (`14e4`).
- Updated `_run_cmd` to integrate the new pause logic for consistent workflow interruptions during script execution.
