The setup wizard was 1205 lines in a single file. Extract the
state-independent helpers (escapeHtml, ratePassphrase, scheduleRate,
entropyText, STRENGTH_LABELS, the Strength interface) into a sibling
setup-helpers.ts. updateStrengthUi stays in setup.ts since it walks the
live wizard state object and would force every caller to thread that
state through.
setup.ts: 1205 → 1137 lines. Pure mechanical extraction; no behavior
change. Existing tests are the safety net (24 vitest files, all pass).
