- Store list queries under summer-admin.list:<admin id>:<controller>; me()
and setCurrentUser set the owner, which removes other admins' keys and
the unscoped keys of older builds; nothing is read or written without one
- clearUser removes every stored query, so logout, session expiry and an
unrecoverable 401 (expireSession, now used by main.ts) all clear them
- A list request built from a restored query that fails for any reason
(422, 500, network) forgets the query and loads the plain list once
- A failing URL query keeps the error and offers a reset button
(backend::lang.list.reset_list, en and pl)
- Document remembered list state in docs/backend/lists-and-filters.md
- Rebuild modules/boardwalk/dist
