OpDebug::log() reports interrupt delinquency statistics (numInterruptChecks, delinquencyInfo) to the slow query log, but OpDebug::append() omits them from system.profile documents, so clients cannot observe per-operation delinquency without scraping server logs.

Mirror the log() reporting in append():

• Always emit numInterruptChecks for parentless operations
• Emit delinquencyInfo when ticket-acquisition or overdue-interrupt-check stats are non-zero, skipping acquisition stats inside multi-document transactions as log() does

Only executes when a profile document is written (profiling enabled); no hot-path cost when profiling is off.

Used by the interrupt_delinquency_repro DSI workload (PERF-9773), which harvests per-stage delinquency from shard primaries' system.profile during a run.
