web/admin: decorative display in user’s page breaks in other locales (#13393)

* 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.

* This (temporary) change is needed to prevent the unit tests from failing.

* web/admin: decorative display in user's page breaks in other locales

## What

Move the decorations out of the display string and make them part of the presentation instead:

```
- <small>${item.name === "" ? msg("<No name set>") : item.name}</small>
+ <small>${item.name ? item.name : html`&lt;${msg("No name set")}&gt;`}</small>
```

Also a bit of logic re-arrangement; whenever possible, try to put the fallback condition in the
secondary position. A ternary is appropriate here; the nullish coalescing operator (`??`) is not
triggered by an empty string.

## Why

The decorations are being misinterpreted as HTML markers. The localization function re-interprets
the ampersand a second time, creating the string `&amp;lt;No name set&amp;gt;.

## Testing

- Visit the user administration page in English mode:
  http://localhost:9000/if/admin/#/identity/users
- Create a user but do NOT fill in the Name field (the second field, which lacks an asterisk
  indicating "required.")
- Note that the user shows up, and `<No name set>` is displayed for the user's display name.
- Visit the user administration page in French mode:
  http://localhost:9000/if/admin/?locale=fr#/identity/users
- Note that the user shows up, and `<No name set>` (or, if the field is translated, "Aucun nom
  spécifié") is displayed for the user's display name.
