This pull request introduces support for the new SpaceTech Challenge landing page and its associated email notification flow. The main changes include seeding a new email processor flow (initially disabled), providing a form definition, adding a script for publishing the form to the API, and updating integration tests to verify the new flow.

SpaceTech Challenge Email Flow Integration:

• Added a new migration (20261102010000_space_tech_challenge_email) that seeds the space-tech-challenge-email processor flow for the space_tech_challenge form. This flow is disabled by default and configured to use recipients and template IDs supplied by the environment. [1] [2]
• Updated documentation in docs/data-model.md to describe the new migration and its configuration requirements.

SpaceTech Challenge Form Definition:

• Added a new example form definition in examples/space-tech-challenge.json for collecting challenge submissions, including fields for name, company, email, and challenge description.

Deployment and Testing Automation:

• Introduced a new script publish-space-tech-challenge.ts to idempotently publish the SpaceTech Challenge form definition to the selected Forms API environment.
• Extended integration tests to verify that the SpaceTech challenge email processor flow is seeded in a disabled state with the correct settings.
