feat: add Deployment Jobs, Template Categories, Virtual Machine details and management pages

- Implemented DeploymentJobsPage for managing deployment jobs with filtering and retry functionality.
- Created TemplateCategoriesPage for managing template categories with add, edit, and delete capabilities.
- Developed VirtualMachineDetailsPage to display detailed information about a specific virtual machine.
- Added VirtualMachinesPage for listing, adding, editing, and deleting virtual machines, including linking and unlinking to domains.
