This adds a circuit breaker for uncaught failures in beforeEach. The first failure still goes through the normal ERROR/RESTART recovery path; a second consecutive failure redirects to the static error page instead of looping.
- New before-each-error-recovery module tracks recovery attempts in sessionStorage (with an in-memory fallback).
- ERROR/RESTART routes skip normal guard logic so the counter can accumulate across bounce-backs.
- The counter clears only after a fully successful navigation.
- redirectToStaticErrorPage centralizes hard-error bailout: logs, clears poisoned sessionStorage keys (submittedState, heritage redirect count, recovery count, externalParameterState), then navigates to /fmg/static/error.
- The static error page RESTART flow clears the same sessionStorage keys so bad state does not re-enter the funnel.
- Session storage key strings are centralized in session-storage.js.
- Unit tests cover recovery counting, bailout clearing, and navigation fallbacks.
Expected impact: Stops repeated ERROR → RESTART → ERROR cycles (including corrupt submittedState JSON.parse failures and recurring automation errors in us-east-1/us-east-2) by bailing out to the static error page after one failed recovery attempt.
