Adiciona mecanismo de expiração periódica para jobs que ficam presos nos status received ou processing além de um threshold configurável. - models: novo status StatusTimeout - store: migration v2 com índice em jobs(status); método ExpireStuck que faz UPDATE atômico para os status alvo anteriores ao threshold - expirer: novo pacote com goroutine periódica que chama ExpireStuck e loga WARN quando algum job é expirado - config: campos JobTimeoutMinutes (default 120) e ExpirerIntervalMinutes (default 10), lidos via env vars JOB_TIMEOUT_MINUTES e EXPIRER_INTERVAL_MINUTES - main: instancia e inicia o Expirer no startup - dashboard: card Timeout com contagem; badge neutral na tabela de jobs
