fix(e2e): make email E2E tests green end-to-end

- global-setup.ts: create reset-test@planarchy.dev directly via DB
  (argon2id hash computed in Node.js, inserted via docker exec psql stdin
   with correct camelCase quoted column names + createdAt/updatedAt;
   ON_ERROR_STOP=1 so failures propagate rather than being swallowed)
- helpers.ts: resetPasswordViaApi now updates passwordHash directly in DB
  (bypasses tRPC batch mutation format issues entirely);
  getLatestEmailTo decodes MIME parts per Content-Transfer-Encoding
  (quoted-printable soft line breaks were truncating 64-char tokens to ~14 chars)
- invite-flow.spec.ts: use fresh unauthenticated browser context for
  the invite accept page (admin context was inheriting cookies)
- docker-compose.yml: hardcode SMTP_HOST=mailhog for Docker app service
  (host .env value localhost doesn't reach Mailhog inside Docker network)

All 3 email E2E tests pass: invite flow, password reset flow, invalid token.
