feat: Implement API client and token models with hashing and JWT authentication

- Added ApiClientModel and ApiTokenModel for managing API clients and tokens.
- Introduced ConfigurationDefinitionModel and ConfigurationValueModel for configuration management.
- Created CredentialSecretModel for storing credential secrets.
- Developed DeploymentArtifactModel and DeploymentBatchModel for deployment management.
- Enhanced DeploymentTargetModel and DeploymentTemplateSelectionModel to support template revisions.
- Added TemplateRevisionModel and TemplateVersionModel for versioning templates.
- Implemented ApiClientSecretHasher for secure secret hashing.
- Created ApiTokenService for generating and validating JWT tokens.
- Updated QueueJobService to handle deployment requests with artifacts.
- Configured authentication settings in appsettings.json for JWT and Negotiate authentication.
