## Objective
<!--Describe what the purpose of this PR is. For example: what bug you're fixing or what new feature you're adding-->
See #3425 for part 1 and background.
This PR adds emergency access to the rotation. All new code is hidden behind a feature flag.
The Accounts controller has also been moved to Auth ownership.
## Code changes
<!--Explain the changes you've made to each file or major component. This should help the reviewer understand your changes-->
<!--Also refer to any related changes or PRs in other repositories-->
* **file.ext:** Description of what was changed and why
* **AccountsController.cs:** Moved to Auth ownership. Emergency access validation was added (as well as initializing empty lists to avoid errors).
* **EmergencyAccessRotationValidator.cs:** Performs validation on the provided list of new emergency access keys.
* **EmergencyAccessRepository.cs:** Adds a method to rotate encryption keys. This is added to a list in the `RotateUserKeyCommand` that the `UserRepository` calls so it doesn't have to know about all the domains.
