Summary

Wire retry-delay recording at the findAndModify retry-detection call site for SERVER-107365 (retried writes latency histogram).

Site

src/mongo/db/commands/query_cmd/find_and_modify.cpp (~L471-475)

The retry branch already has the OplogEntry in hand, so compute

millis = Date_t::now() - entry->getWallClockTime()

and call

RetryableWritesStats::get(opCtx)->recordRetriedWriteDelay(millis)

alongside the existing incrementRetriedStatementsCount().

Test

Add one test asserting a retried findAndModify lands one sample in the expected bucket (SERVER-107365 Task 3: one test per call site).
