PHOENIX-7945 Fix OrphanDeleteMarkerCompactionIT timeout on HBase 2.6 (addendum)#2565

Conversation
…(addendum) HBase 2.6 moved Admin.flush() from ZK-based execProcedure to ProcedureV2 (FlushTableProcedure). The RemoteProcedureDispatcher uses a DelayQueue keyed on EnvironmentEdgeManager.currentTime() with a default 150ms delay. When ManualEnvironmentEdge is injected and only the blocked test thread can advance time, the dispatch item never expires — deterministic deadlock. Set hbase.procedure.remote.dispatcher.delay.msec=0 so the dispatch item expires immediately, consistent with the fix already applied to 10+ other Phoenix test classes after PHOENIX-7353/7354.

Summary
hbase.procedure.remote.dispatcher.delay.msec=0toOrphanDeleteMarkerCompactionIT.doSetup()to prevent deterministic deadlock on HBase 2.6 CI profile.Root Cause
HBase 2.6 (HBASE-26867) moved
Admin.flush()from ZK-basedexecProcedureto ProcedureV2 (FlushTableProcedure→FlushRegionProcedure). TheRemoteProcedureDispatcheruses aDelayQueuekeyed onEnvironmentEdgeManager.currentTime()with a default 150ms delay. WhenManualEnvironmentEdgeis injected and only the blocked test thread can advance time, the dispatch item never expires — deterministic deadlock causing 120s timeout.Fix
Set
hbase.procedure.remote.dispatcher.delay.msec=0so the dispatch item expires immediately from theDelayQueue. This is consistent with the fix already applied to 10+ other Phoenix test classes after PHOENIX-7353/7354.Test plan
