Hide strategy error messages for non-admins

[kenkunz]

Goal

As a non-admin user viewing strategies, I don't want to see error messages that are only relevant to technical users, so that I am not distracted unnecessarily by aspects of strategy execution that are not relevant to me.

Acceptance criteria

1. For a non-admin user viewing strategy index, a strategy with errors should not include an [Error] badge in the strategy tile (with the exception of strategies that failed to return a valid metadata response).
2. For non-admin user viewing the strategy overview page of a strategy with an error, the error alert should not be displayed.
3. For an admin user viewing strategy index, a strategy with errors should include the [Error] badge as it does today. In addition, the tooltip should include a note that the error message is only displayed for admin users.
4. For admin user viewing the strategy overview page of a strategy with an error, the error alert should continue to be displayed. In addition, it should include a note that the error is only displayed for admin users.
