Add update functionality for cloud-init templates in the dashboard

Browse Source 
Implement a new API endpoint to update existing cloud-init templates, allowing users to modify template attributes such as name, user_data, meta_data, and network_config. Enhance the dashboard UI to include an update button for templates, along with associated JavaScript for handling update requests. This improves user experience by enabling direct template modifications from the interface.
