fix(web): allow deploy-skew recovery reload in private browsing

[sentry]

The reloadForSkew function in ServiceWorkerRecovery previously returned early when sessionStorage was unavailable (e.g., in private browsing mode or due to storage quota issues). This prevented the intended deploy-skew recovery reload, leaving users on a broken page displaying TypeError: Cannot read properties of undefined (reading 'call').

This change introduces a module-level reloadScheduled flag to handle in-page deduplication of reload requests. With this flag in place, window.location.reload() can now proceed even if sessionStorage fails. A hard reload reinitializes the module, resetting the reloadScheduled flag, which prevents any risk of an infinite reload loop.

This ensures that users in private browsing mode or those encountering sessionStorage issues will now receive the necessary page reload to recover from deploy-skew errors, improving resilience and user experience.
