fix(security): raise password minimum to 12 chars, hide raw error messages, add audit script

- Password validation: min(8) → min(12) across auth.ts, user-procedure-support.ts,
  and invite.ts (aligns with NIST SP 800-63B modern recommendations)
- Error boundary: stop rendering raw error.message which could leak internal
  details; always show the generic fallback text
- Add `pnpm audit` script (--audit-level=high) for dependency vulnerability scanning
