   ### What changes were proposed in this pull request?
   
   1. JVMQuakeSuite: CELEBORN-2324 fixed threshold unit conversion 
(microseconds ->
      milliseconds), causing the 1s dump threshold to require ~1s of 
accumulated GC
      time. In the tight allocation loop with runtimeWeight=1, the bucket decays
      when gcTime < runTime, so the test hangs indefinitely. Fix by using 
ms-scale
      thresholds (1ms dump, 1h kill), runtimeWeight=0, and 10ms check interval.
   
   2. LifecycleManagerUnregisterShuffleSuite: The suite's unregister-shuffle 
tests consistently wait the full 120s eventually timeout because 
removeExpiredShuffle() only runs every 60s. Reduce the check interval to 1s so 
the delayed-unregister path fires quickly.
