fix(visualization): address workspace review feedback

[dsk-dev-ai]

Applies Sourcery review feedback from the Phase 6.9 workspace PR:

• ResearchContextSelector: drop the redundant aria-label on the context <select> (the <label htmlFor> association already provides the accessible name, avoiding double announcements).
• fixtureDataSources: unify abort handling behind a single shared abortAware helper in lib/workspace/dataSources.ts (used by both interval and whole-dataset loaders via resolveFixture), removing the duplicated local wrapper.
• Add focused abortAware tests (run resolver when not aborted; reject with AbortError without running the resolver when already aborted).

Validation: lint, typecheck, 725 vitest + 1606 pytest, turbo build, git diff --check all green.

Summary by Sourcery

Unify abort-aware handling for workspace fixture data sources and tighten workspace UI accessibility.

Enhancements:

• Introduce a shared abortAware helper in workspace dataSources and use it for both constant fixture loaders and interval-based loaders to centralize AbortSignal handling.
• Simplify ResearchContextSelector markup by relying on the existing label association instead of a redundant aria-label on the select element.

Tests:

• Add focused unit tests for abortAware to verify it runs the resolver when not aborted and rejects with an AbortError without invoking the resolver when already aborted.

Reviewer's Guide

Centralizes abort handling for workspace fixture data sources via a shared abortAware helper (with focused tests) and removes a redundant aria-label from the research context selector for better a11y.

File-Level Changes

Change	Details	Files
Introduce a shared abortAware helper for workspace loaders and use it to implement resolveFixture and demo fixture data sources.	Add abortAware helper that short-circuits aborted signals with an AbortError before invoking the resolver. Refactor resolveFixture to delegate to abortAware while preserving the fixture-based loader behavior. Replace the local abortAware implementation in fixtureDataSources with imports of the shared abortAware and resolveFixture from the workspace dataSources module.	apps/web/src/lib/workspace/dataSources.ts apps/web/src/components/workspace/fixtureDataSources.ts
Add focused tests for abortAware behavior and keep resolveFixture tests for fixture resolution.	Import abortAware and vi from vitest in the workspace dataSources test file. Add tests to verify abortAware calls the resolver when the signal is not aborted and rejects with AbortError without calling the resolver when already aborted.	apps/web/src/lib/workspace/dataSources.test.ts
Simplify research context selector accessibility by relying on the explicit label association.	Remove the redundant aria-label from the research context element so the label htmlFor provides the accessible name.	apps/web/src/components/workspace/ResearchContextSelector.tsx
