feat(client): port Learning Hub to React

Minimum-viable port of the user-facing Learning Hub at /app/learning.
Sidebar nav flipped to available in the same commit.

client/src/pages/Learning.tsx
  Three-screen flow: search + category pills drive a feed grid; clicking
  a card opens the viewer; viewer shows body + progress + quiz (if any).

  Feed: one query key per filter — ['learning-feed'], ['learning-category',
  slug], or ['learning-search', q] — so React Query caches each view
  independently and flicking between categories is instant after the first
  load. Search hits /api/learning/search; category filter hits
  /api/learning/category/:slug; default hits /api/learning/feed?limit=30.

  Viewer: body rendered as pre-wrap text intentionally. The vanilla tree
  uses DOMPurify (CDN-loaded) to render HTML bodies; adding that dep to
  the client bundle is a follow-up. Authored content is still clinical
  info, so plain-text preservation is acceptable for this commit — no
  content is lost, just unstyled. Presentations (content_type === 'presentation')
  link to the legacy viewer at /#learning/:slug — Marp slide rendering is
  its own port.

  Quiz: supports single-choice, multi-select, and true/false. Answers
  tracked via { optionId?, optionIds: Set<number> } per question so the
  same state shape drives both radio and checkbox rendering. Submit POSTs
  to /api/learning/submit-quiz; results screen shows per-question verdict
  with correct answer + why-incorrect + general explanation — same fields
  the vanilla showQuizResults renders. Retake wipes the answer map;
  Back-to-Feed returns to the list.

  Progress list reads content.progress[] directly from the content response
  — last 5 attempts, color-coded green/amber at 70%.

shared/types.ts + client/src/shared/types.ts — additive:
  LearningCategory/LearningCategoriesOk, LearningFeedRow/LearningFeedListOk,
  LearningOption/LearningQuestion/LearningProgressEntry/LearningContentFull/
  LearningContentOk, QuizAnswer/QuizResultEntry/QuizSubmitOk. Keys match
  the wire shape server routes return (snake_case for DB columns).

e2e/tests/learning-react.spec.js — three smoke tests:
  shell renders, feed shows items OR empty-state (no crash on empty DB),
  typing into search fires /api/learning/search.

Client tsc -b, server tsc --noEmit, and vite build all pass locally.
Bundle 435.44 kB / 123.81 kB gzipped (+10 kB over Settings complete).
