FIX: Use placeholder for "everyone" group name in category permissions (#37724)

Automatic group names are translated to the forum's default locale (e.g.
"jeder" in German). The category permission warning messages and
inherited permission tooltips were hardcoding the English "everyone"
name, which created a mismatch when the admin UI showed the localized
group name.

Replace the hardcoded "everyone" in the four affected translation
strings with a `%{everyone_group}` placeholder and pass the actual group
name from the permission data at each call site.
