Ensure robust handling of missing Capacity.json file
Added logic across multiple files to dynamically create a default empty `Capacity.json` file when it is missing, ensuring the application remains functional. Updated `Capacity.razor` to log errors comprehensively and provide a fallback in-memory capacity object. Refactored `Calculations.cs` and `CalculateProposal.cs` to consistently handle missing files and log warnings. Improved the `Response.razor` UI by clarifying the purpose of the "Edit Capacity" button. Enhanced error handling and logging to track file creation and ensure fallback mechanisms are in place for seamless operation.
