research UI: fix 3 lint errors — async wrapper + escape apostrophe

Push right after ec1ddc6 tripped three eslint errors on the same-commit
lint pass. All three are cosmetic in behavior:

- ResearchList.tsx:48 + ResearchCanvas.tsx:64 — setState was called
  synchronously at the top of a useEffect. Wrap the body in an inner
  async load() and call setState inside it; effect still returns the
  cleanup for the alive-flag guard.
- ResearchWizard.tsx:207 — bare apostrophe in JSX text ("workspace's").
  Replace with ' to satisfy react/no-unescaped-entities.
