## Objective

<!--Describe what the purpose of this PR is. For example: what bug you're fixing or what new feature you're adding-->
Final Client changes for Key Rotation Improvements. 

- Introduces a new `KeyRotationService` that is responsible for owning rotation process.
- Moves `Send` re-encryption to the `SendService` (`KeyRotationService` shouldn't have knowledge about how domains are encrypted).
- Moves `EmergencyAccess` re-encryption to the `EmergencyAccessService`.
- Renames `AccountRecoveryService` to `OrganizationUserResetPasswordService` after feedback from Admin Console
