Switch from z.instanceof(FormData) to uploadFileSchema (zod-form-data)
so the OpenAPI generator produces a proper multipart/form-data spec
with typed fields (zip as binary, applicationId, dropBuildPath).
Regenerate openapi.json with the drop-deployment endpoint included.
Enable file upload deployments via the public API, unlocking CI/CD workflows
similar to `railway up`. Users can now programmatically deploy by uploading
zip archives.
Depends on: Dokploy/trpc-openapi multipart/form-data support
