Replace the primary "Disabled/Enabled" Herald Rule filter with "Active/Inactive", considering author status

Summary:
Ref T13216. See PHI947. In Herald, Personal rules do not run if their author's account is disabled.

This isn't communicated very clearly in the UI, and the way the SearchEngine/Query are set up isn't great.

Define "active" as "rule will actually run", which specifically means "rule is enabled, and has a valid (non-disabled) author if it needs one".

Change the meaning of the "Active" default filter from "rule is enabled" to "rule is enabled, and has a valid author if it needs one".

Refine the status badge on the view controller to show this "invalid author" state.

Tweak the language for "Disable/Enable" to be more consistent -- we currently call it "disabled" in some cases and "archived" in others.

Test Plan:

• Disabled a user account and saw their personal rules behave properly with the new filters/options/view controller.
• Disabled/enabled a rule, saw consistent text.
