Context behind the change

• Replaced the fortune job creation endpoint with a generic job creation endpoint that accepts a manifest JSON body.
• Introduced JobManifestDto to encapsulate job details including manifest.
• Updated JobService to handle different job types based on the manifest provided.
• Modified tests to reflect changes in job creation logic and added validation for new manifest types.
• Enhanced ManifestService to validate and upload manifests for various job types including CVAT and HCaptcha.
