In the left-nav rail SyncStatus, the pause button rendered as its own bottom block, so with only
deep-history pending (idle) it dropped to a lonely line under 'N without full history'. Now it sits
right-aligned on the primary status row — the sync-state line when there is one, otherwise the
'N without full history' row — via flex justify-between. No change to the all-synced state.
