refactor(platform): remove forms, templates, and creators features

Remove three standalone features and their supporting code:
- Forms: form-deployment pages, API routes, execution path, and docs.
- Templates: the template gallery (landing + workspace) and template APIs.
- Creators: creator-profile routes and contracts.

Add a super-user permissions module (lib/permissions/super-user) and an
organizations API contract; update the audit/db/testing packages, billing,
and the session/theme providers accordingly.

     When you click <strong>Run</strong> in the editor, the Start block renders the Input Format as a form. Default values make it easy to retest without retyping data. Submitting the form triggers the workflow immediately and the values become available on <code>&lt;start.fieldName&gt;</code> (for example <code>&lt;start.sampleField&gt;</code>).

-    Form deployments render the Input Format as a standalone, embeddable form page. Each field becomes a form input with appropriate UI controls—text inputs for strings, number inputs for numbers, toggle switches for booleans, and file upload zones for files.

-    When a user submits the form, values become available on <code>&lt;start.fieldName&gt;</code> just like other entry points. The workflow executes with trigger type <code>form</code>, and submitters see a customizable thank-you message upon completion.
