chore: update pnpm-lock.yaml after dependency installation

- Add safeRequestSubmit helper function with null checks and browser compatibility fallback
- Replace all form.requestSubmit() calls with safeRequestSubmit(form)
- Dispatch submit event as fallback for browsers without requestSubmit support
- Fixes TypeError: t.requestSubmit is not a function on /s/:surveyId route
