Add update script, enhance admin features, and improve styles

- Created a PowerShell script (update.ps1) for automating the process of pulling the latest repository changes, stopping, building, and starting the Docker Compose stack.
- Updated App.jsx to include new admin sections for alarms and integrations, added state management for runner jobs, and enhanced permission checks.
- Extended the API module (api.js) with new endpoints for managing integrations and runner jobs.
- Improved CSS styles for a more compact and responsive layout in the admin interface, focusing on source and datapoint cards.
