v1.4.34.5 — audit follow-on: critical-path tests + iOS textarea zoom

Follow-on to v1.4.34.4.

Tests:
  24 new integration tests across 5 files closing the highest
  critical-path gaps the test-coverage audit flagged:
    - auth-password-change.test.ts pins the v1.4.34.3+
      destroyAllSessions three-transport revocation contract.
    - admin-reset-password.test.ts mirrors the same shape for
      admin resets.
    - withings-oauth.test.ts covers connect / callback / disconnect
      + state-token replay rejection.
    - passkey-register.test.ts covers register-options +
      register-verify + tampered-attestation + challenge single-use.
    - cache-invalidation-coverage.test.ts grids the IW-G
      invalidation matrix across 5 write surfaces.
  Integration suite: 197/50 → 222/55. tsc + lint clean.

Mobile:
  Five textareas no longer trigger iOS Safari zoom-on-focus. The
  Coach composer, bug-report description, admin feedback note,
  medication-side-effects notes, and medication-intake JSON
  import all shipped text-sm (14 px). iOS Safari zooms whenever
  an input renders below 16 px. Switched each to
  `text-base sm:text-sm` so mobile clears the floor while desktop
  keeps the compact look.
