fix(inventory): drop leaking badge pending-counter; trust server active set

sendActiveBadges incremented pendingUpdatesRef on every edit, and the BadgesEvent
handler skipped applying the server's active badges while the counter was > 0,
decrementing once per BadgesEvent. The assumption was "one BadgesEvent echo per
SetActivatedBadges" — but the emulator's UserWearBadgeEvent answers with a
UserBadgesComposer room broadcast, NOT a BadgesEvent, so nothing ever decrements
the counter. It leaks upward with every toggle/reorder/swap and then silently
drops legitimate later BadgesEvent updates (the server-authoritative active set
never reapplies). Remove the counter and always apply the server's active badges
on BadgesEvent (edits are already persisted server-side, so this is correct).
