Phriction: clarify its search results as "Wiki page"

Summary:
This patch changes a bit how your search results from Phriction
are described in the autocomplete component (the "Typehead"):

{F276843}

After this change, Phriction search results will also contain the word
"Wiki page" so that users can better understand what the result
actually is. Just like a Diffusion repository mentions that it's
a "Repository", and just like a Project mentions that it's a
"Project" and so on.

Before this change, the Typehead entries were only mentioning
the slug of that wiki page.

| Before    | After     |
| {F274820} | {F272278} |

It's unclear if the previous behavior was a mistake (since the
internal parameter of the Typehead is called "type", and so, it
is supposed to mention the application type, not the slug.

Anyway, as a compromise, the slug is still mentioned.

To be honest this is just an excuse to put the middle dot /
aka interpunct character in this project again. Yeah, here the
middle point was used as separator. The apparent reason is:
because the middle point was already in use elsewhere in Phorge.
The real reason is: I'm a lobbyist in a corporation that sells
interpuncts worldwide as our core business, and so, I designed
thisvil plan to put the following middle point - again - in
Phorge (evil laugh).

Closes T15213

Test Plan:
- Search "Change Log" in the up-right bar (or similar)
- You see "Wiki Page · change_log/" (or similar)
