core: nil-guard balTransitionStats in reportBALMetrics

Browse source 
Mirrors the nil-check already used in buildSlowBlockLog. The previous
unguarded access was safe today only because parallel_state_processor
short-circuits on error before the metrics path is reached, but the API
contract was fragile — a future caller could reach reportBALMetrics
without an established balTransitionStats and panic.
