web/user: ensure modal container on user-settings page is min-height: 100% (#13402)

* web: Add InvalidationFlow to Radius Provider dialogues

## What

- Bugfix: adds the InvalidationFlow to the Radius Provider dialogues
  - Repairs: `{"invalidation_flow":["This field is required."]}` message, which was *not* propagated
    to the Notification.
- Nitpick: Pretties `?foo=${true}` expressions: `s/\?([^=]+)=\$\{true\}/\1/`

## Note

Yes, I know I'm going to have to do more magic when we harmonize the forms, and no, I didn't add the
Property Mappings to the wizard, and yes, I know I'm going to have pain with the *new* version of
the wizard. But this is a serious bug; you can't make Radius servers with *either* of the current
dialogues at the moment.

* web/admin: ensure modal container on user-settings page is min-height: 100%

## What

Add a min-height and auto-scroll directives to the CSS for the main section of the user-settings
page.

```
+                .pf-c-page__main {
+                    min-height: 100vw;
+                    overflow-y: auto;
```

## Why

Without this, Safari refused to render any pop-up modals that were "centered" on the viewport but
were "beneath" the rendered content space of the container. As a result, users could not create new
access tokens or app passwords. This is arguably incorrect behavior on Safari's part, but 🤷‍♀️.
Adding `overflow-y: auto` on the container means that if the page is not long enough to host the
pop-up, it will be accessible via scrolling.

## Testing

- Using Safari, Visit the User->User Settings, click "Tokens and App Passwords" tab, and click
  "Create Token" or "Create App Password"
- Observe that the dialog is now accessible.
