* Device DB cache limit dropdown, shared between the Android and Desktop settings screens. Lowering the limit below the

* number of currently-cached device databases evicts the least-recently-used ones and permanently deletes their local

* history, so a lower value is gated behind a confirmation showing how many devices would be affected. Raising or

* leaving the limit unchanged never evicts anything and applies immediately.
