test(admin): list state round trip and storage coverage

- Form back, cancel, save-and-close and delete land on the list with the stored query; every list request after the return carries it
- listState helpers: key prefix, malformed stored values removed, empty query stores nothing, throwing storage
- ListView entry: URL wins, cleared controls forget the query, same-list navigation, 422 forgets, page clamp
- Logout removes every list key and keeps the sidebar preference
