fix: persist confirm-tx view across popup close/reopen

The confirm-tx view was not in RESTORABLE_VIEWS, so closing and
reopening the popup would fall back to the main view, losing the
pending transaction confirmation.

Save pendingTx data to state.viewData when showing confirm-tx and
add confirm-tx to the set of restorable views with proper restore
logic.

Closes #77
