* Fix references to `crypto-api/verification`
This is supposed to be an internal module; use the front door instead.
* `IRecoveryKey` -> `GeneratedSecretStorageKey`
`IRecoveryKey` is just a backwards-compatibility alias for
`GeneratedSecretStorageKey`
* `ISecretStorageKeyInfo` -> `SecretStorage.SecretStorageKeyDescription`
Again, same thing
* `IPassphraseInfo` -> `SecretStorage.PassphraseInfo`
* Remove unused import restriction exceptions
