web: improve password experience

This commit disassembles PromptStage and places function that don't
need a reference to the PromptStage object into a collection of
maps between the Stage type and the prompt associated with it.  (In
a better world, this would be a great place to try some post-Midgard
mplementation of itemtype/itemid/itemprop).

This surfaced the nature of the relationship between Password and
Password (Repeat), allowing us to modify both to show password
strength and password matching for the "change password" dialog.

 This is the default UI for the authentik server. The documentation is going to be a little sparse
 for awhile, but at least let's get started.
 
+# Standards

+-   Be flexible in what you accept as input, be precise in what you produce as output.
+-   Mis-use is always a crash. A component that takes the ID of an HTMLInputElement as an argument
+    should throw an exception if the element is anything but an HTMLInputElement ("anything" includes
+    non-existent, null, undefined, etc.).
+-   Single Responsibility is ideal, but not always practical. To the best of your obility, every
+    object in the system should do one thing and do it well.
