Log localStorage write failures in local_storage_set (#8062)

Browse Source 
Log `localStorage` write failures in `local_storage_set`

**Description**  
This PR improves `local_storage_set()` logging in
`eframe/src/web/storage.rs`.

It logs:
- write failures with key and browser error
- unavailable local storage

This helps diagnose web persistence issues such as `QuotaExceededError`
when `localStorage.setItem()` fails.
