This update improves the robustness of security signal hashing by replacing the static fallback secret with a process-scoped random key when `AUTH_SECRET` is missing. It also enhances test reliability by using randomized credentials and CSRF tokens. - Replace static `HASH_FALLBACK_SECRET` with a dynamically generated `randomBytes` hash to prevent deterministic signal hashing in environments without a configured secret. - Add a console warning to notify when the system falls back to a process-scoped hash key due to a missing `AUTH_SECRET`. - Update `authCredentialEnvelope.test.ts` to use random bytes for both the password and CSRF token instead of hardcoded strings. - Import `randomBytes` in `clientSignals.ts` for secure key generation.
