🧭 fix: Restore Post-Auth Navigation After Silent Token Refresh (#12025)

* chore: Update import path for StartupLayout in tests

* 🔒 fix: Enhance AuthContext to handle stored redirects during user authentication

- Added SESSION_KEY import and logic to retrieve and clear stored redirect URLs from sessionStorage.
- Updated user context state to include redirect URL, defaulting to '/c/new' if none is found.

* 🧪 test: Add tests for silentRefresh post-login redirect handling in AuthContext

- Introduced new test suite to validate navigation behavior after successful token refresh.
- Implemented tests for stored sessionStorage redirects, default navigation, and prevention of unsafe redirects.
- Enhanced logout error handling tests to ensure proper state clearing without external redirects.

* 🔒 fix: Update AuthContext to handle unsafe stored redirects during authentication

- Removed conditional check for stored redirect in sessionStorage, ensuring it is always cleared.
- Enhanced logic to validate stored redirects, defaulting to '/c/new' for unsafe URLs.
- Updated tests to verify navigation behavior for both safe and unsafe redirects after token refresh.
