This pull request introduces support for the SpaceTech challenge form, including its definition, deployment tooling, and notification email flow. It seeds a disabled notification flow for the new form, provides a JSON definition, adds a publication script, and updates documentation and tests to cover these changes.

SpaceTech challenge form and notification flow:

• Added a new migration (20261102010000_space_tech_challenge_email) to seed a disabled ProcessorFlow for the SpaceTech challenge form, which will email all submissions to a fixed recipient list using environment-supplied settings. This flow is disabled by default and should be enabled after configuration and redeployment. [1] [2]
• Added a new form definition for the SpaceTech challenge in examples/space-tech-challenge.json.
• Added a publishing script (scripts/publish-space-tech-challenge.ts) to idempotently register, version, and publish the SpaceTech challenge form to the Forms API, using environment variables for configuration.

Documentation and testing:

• Updated documentation in docs/data-model.md to describe the new notification flow and its configuration.
• Added integration test to verify that the SpaceTech challenge email flow is seeded as disabled with settings left to the processor environment.

Policy clarification:

• Clarified machine identity handling in test/policies.spec.ts by adding tests for the machine identity flag and its effect on actor normalization.
