feat(dashboard): pending guild names count on the Review Queue and Guilds badges

The dashboard snapshot counts guilds whose name waits for moderation; the moderation counts (WebSocket and
/api/moderation/counts) include it, the Review Queue badge adds it for staff with guilds_manage, and the Guilds menu
entry has its own badge. Check: create a guild with a name off the allow list: both badges go up; approve it: they
go down.
