Enhance risk API documentation and error handling

- Updated API documentation for risk endpoints to include optional caching headers and error catalog references.
- Added a new error catalog JSON file to standardize error responses.
- Improved explainability documentation with sample outputs for console and CLI.
- Added SHA256 checksums for new sample files related to explainability.
- Refined AocGuard tests to utilize a helper method for generating test JSON, improving readability and maintainability.
- Updated runbook references to ensure consistency in sprint documentation.
- Introduced stub implementations for MongoDB storage interfaces and options, laying groundwork for future development.
- Disabled analytics in Angular CLI configuration for privacy considerations.
