    Rework hardcoded policy in admin dash

    Since the content in a Dashboard is not hardcoded, having hardcoded
    policy checks to specific services at the dashboard level is wrong.
    The Dashboard was designed to evaluate all panels to determine policy
    so this type of thing could be avoided. This patch moves the content
    specific policy checks to the panels where they apply.

    Additionally, this fix uncovered another bug where policy_rules are
    wrapped in a list regardless of format. This patch adds a check and
    only wraps where necessary.
