This avoids recomputation and provides a single source of truth.
Performance is also better now.

A typo in an attribute could be a source of waste of time investigating the reason for the not
expected behavior. This gives an immediate feedback in case of error.

The wrong attribute name prevents the toggle switch in the subscriptions dropdown to work.

For some reason (at least to me, unknown), the notifications returned by useNotificationsCenter
hook is initially undefined.
This means that when the last notification is removed, the hook returns undefined and the
navigation to the notifications center is not triggered.
Changed the check: when notifications is not undefined, even if an empty array, the navigation
must be triggered.

When the condition is met, (either due to error for bad navigation or because the notification is
removed), the correct action is to go back to previous page: pushing a new page injects into the
history a sort of infinite loop-back navigation, as a result the back button does not work.

Add support for nothunks == 0.3.*

The deadlock was caused by holding the app state reference (from
get_app_state_readonly()) while cloning block data inside create_resource().
Block cloning is expensive and was blocking other subscription threads trying
to acquire locks on the same app state, even with 2048 DashMap shards.

Changes:
1. Clone block_data BEFORE acquiring app state lock
2. Explicitly drop(block_app_state) immediately after create_resource()
   to release the shared lock early

This eliminates lock hold time during the expensive clone operation, allowing
subscription threads to proceed concurrently without blocking on slow clones.

Thread backtraces showed lock_exclusive_slow() with only 2-3 concurrent
inserters despite 2048 shards, indicating the issue was lock hold duration
(expensive clone) not shard collision probability.

This function allows to verify that a particular block hash matches
the one recorded in the big ledger peer snapshot file
when syncing in `GenesisMode`.
