This is to avoid including app-specific functionality in storage and avoid circular imports. The following policy is now in effect: modules from `storage` namespace must not import from `apps` namespace. In most files, the change only involves changing import paths. A minor refactor was needed in case of webauthn: basic get/set/delete functionality was left in storage.webauthn, and more advanced logic on top of it was moved to apps.webauthn.resident_credentials. A significant refactor was needed for sd_salt, where application (and UI) logic was tightly coupled with the IO code. This is now separated, and storage.sd_salt deals exclusively with the IO side, while the app/UI logic is implemented on top of it in apps.common.sd_salt and apps.management.sd_protect.
