fix: try/catch access to localStorage within __NEXT_APP_ISR_INDICATOR useEffect (#72362)
### What?
Under certain circumstances, the Storage APIs, such as local storage,
are not available.
For example, the Brave browser allows users to block `all cookies`,
which forbids access to local storage.

### Why?
When access to local storage fails, the development mode page crashes,
leading to the `Application Error` view.
### How?
Wrap on a try/catch the local storage access done within a use-effect,
under `__NEXT_APP_ISR_INDICATOR`.
There is another local storage access point, but that one is done as
part of `processMessage`, which is called within a `try/catch` block
already.
