What type of PR is this?

Bug fix

What this PR does / why we need it:

• Makes the public pnpm type:check command validate the root app, @datarecce/ui, and @datarecce/storybook with each workspace's own tsconfig.json.
• Adds a non-recursive Storybook leaf command and includes its stories, configuration, Vitest config, and required shared declarations in the Storybook TypeScript program.
• Fixes the package-boundary and ES target errors exposed by those checks without aligning workspace targets or libs.
• Preserves the existing pre-push and UI release callers, which now invoke the aggregate command automatically.

Which issue(s) this PR fixes:

Closes DRC-3217

Special notes for your reviewer:

Failure propagation was proven with a temporary Storybook-only type error: before this change, the public root command exited 0 while the direct Storybook check exited 1; after aggregation, the public command exited 1. The probe was removed before committing.

Verification:

• cd js && pnpm lint — 667 files checked
• cd js && pnpm type:check — root, UI, and Storybook all passed
• cd js && pnpm test — 3,983 passed, 5 skipped
• cd js && pnpm run build — production build passed
• Pre-push hook — aggregate type-check plus 1,858 affected tests passed

Does this PR introduce a user-facing change?:

No.

NONE

Pull request overview

This PR strengthens the JS monorepo’s TypeScript validation by making pnpm type:check run tsc for the root app, @datarecce/ui, and @datarecce/storybook using each workspace’s own tsconfig.json, and updates code to be compatible with Storybook’s ES2020 type-checking constraints.

Changes:

• Aggregate pnpm type:check to run per-workspace checks, and add a dedicated Storybook type:check script.
• Fix ES-target typing gaps by replacing Object.hasOwn / Object.groupBy usage and introducing a small hasOwn helper.
• Update Storybook TS program inputs (includes shared declarations + required UI sources) and adjust UI tests to use colocated test utilities.
