useUserGroups: consolidate 4 dedup'd CatalogGroupsComposer call sites

Four independent components used to send 'new CatalogGroupsComposer()'
on mount and listen for GuildMembershipsMessageEvent:

  - useCatalog (writing into catalogOptions.groups)
  - CatalogLayoutGuildForumView
  - CatalogGuildSelectorWidgetView
  - WiredSelectorUsersGroupView
  - WiredConditionActorIsGroupMemberView

Each fired its own request and re-listened independently. With four
of them mounted in the wired-tools panel during a builder session,
the same packet went out four times.

New useUserGroups() hook wraps the request/response pair with
useNitroQuery (queryKey ['nitro', 'user', 'groups'], staleTime
Infinity — guild membership is session-stable). All four consumers
now read 'const { data: groups = [] } = useUserGroups()' and React
Query dedups: one composer at the first mount, all subsequent mounts
get the cached array.

Drops 'groups' from ICatalogOptions and the corresponding listener +
prev-state-merge from useCatalog — no remaining consumer reads it.
