revert(orbit): drop maxPending cap feature, keep suggestion mute

The pending counter desynced from the actual approval list (state.queue
holds approved items as history, so the count never decreased after a
host approve). The host-pushed pendingApprovalCount workaround didn't
hold up under live testing either, so we're rolling the whole cap
feature back rather than ship something flaky.

What's gone:
- OrbitSettings.maxPending + state.pendingApprovalCount
- cap branch in applyOutboxSnapshotsToState (now back to mute-only)
- maxPending number input in settings popover
- pending counter chip in OrbitQueueHead
- 'cap-reached' branch in evaluateOrbitSuggestGate / OrbitSuggestGateReason
- cap-related toasts in ContextMenu / useOrbitSongRowBehavior
- cap-related i18n keys (suggestBlockedCap, settingMaxPending*, pendingCounter*)
- cap CSS (.orbit-queue-head__pending, .orbit-settings-pop__number)

What stays: per-guest suggestion mute (works correctly) and everything
that fed into both features (OrbitState.suggestionBlocked,
setOrbitSuggestionBlocked, evaluateOrbitSuggestGate, the participants
popover Mic/MicOff toggle, the suggestBlockedMuted toast).
