List sandbox development professional-service projects

Returns deterministic sandbox project, requirement, consultant-task, submission-evidence, milestone, and design-change summaries when the authenticated automation client has development_professional_services.projects.read. External URL: /v1/development-professional-services/current/projects. Current Next.js implementation path: /api/platform/v1/development-professional-services/current/projects. This read-only route does not require Idempotency-Key and never exposes professional contact details, raw documents, private comments, authority credentials, raw design diffs, write controls, or live provider integrations. Document uploads, authority submissions, consultant-task writes, milestone writes, and design-change approvals remain explicitly deferred.
