cli: fix ts-expect-error import in cli/commands/portal/schema.ts

Tracking issue for a TODO found in `packages/cli/src/cli/commands/portal/schema.ts`:

```ts
// @ts-expect-error - @todo - fix this import
```

Investigate and properly fix the typing issue instead of relying on `@ts-expect-error` for this import.

Start in packages/cli/src/cli/commands/portal/schema.ts and inspect the import marked with @ts-expect-error, along with the type error it suppresses. Correct the typing issue without relying on that directive, then run the relevant TypeScript checks and confirm the file builds cleanly.
