- Created a new migration to add the MachineDescriptions table with necessary fields and constraints. - Updated the MarechaiContext to include DbSet for MachineDescriptions and configured its relationships. - Implemented the MachineDescription model to represent descriptions for machines. - Enhanced MachinesController to manage descriptions, including endpoints for retrieving, creating, updating, and deleting descriptions. - Added a new Razor component for managing machine descriptions in the admin panel. - Updated the Machines view to display descriptions and integrated the service layer for fetching and managing descriptions. - Implemented service methods for handling descriptions in MachinesService.
