🔥 Remove PowerGrid and related dependencies

- ❌ Deleted PowerGrid configuration file.
- 🔄 Removed `power-components/livewire-powergrid` and its dependencies (e.g., `simplesoftwareio/simple-qrcode` and `calebporzio/sushi`) from `composer.json` and `composer.lock`.
- 🧼 Cleaned up references to PowerGrid in CSS, JS, tests, and package files.
- 🛠️ Refactored `SecurityMonitor` to eliminate unused methods (`getAttemptsFromIp` and `isIpSuspicious`) dependent on deprecated functionality.
