chore(deps): upgrade TypeScript 6 + @hookform/resolvers 5 (#80)

* chore(deps): upgrade TypeScript 6, @hookform/resolvers 5; add CSS module declaration

- typescript 5.9 → 6.0 (major): requires declare module '*.css' for side-effect
  imports — TypeScript 6 added TS2882 check that Next.js types don't cover yet
- @hookform/resolvers 4.1 → 5.2 (major): no breaking changes in our usage
- recharts pinned at ^2.x (recharts 3 has breaking type changes in chart.tsx
  that require a dedicated fix — deferred to It5)

Closes #75
Closes #76

* ci: upgrade to Node 24 + npm 11; remove hardcoded JWT fallbacks

- node-version 22 → 24 (Node 24 LTS, latest stable)
- Add 'npm install -g npm@11' in all 3 jobs to match local dev environment
  (npm 10 vs npm 11 generate incompatible lockfiles — deduplication differs)
- Remove hardcoded Supabase demo JWT fallbacks (CWE-321); fail explicitly
  instead if supabase status does not return keys (supabase CLI ≥ v1.23
  always returns keys after supabase start succeeds)

* chore: format CLAUDE.md with prettier

CLAUDE.md was previously gitignored; now tracked, prettier check in CI
catches formatting issues.
