[PR] [SERVER] Close sessions for terminated engine applications [kyuubi]

["moelhoussein (via GitHub)" <gi...@apache.org>]

   ### Why are the changes needed?
   
   When an engine application terminates, operations can fail with a generic transport error even though Kyuubi already knows the application has stopped.
   
   This patch reports the application details, interrupts pending RPCs, and closes the session when the application state is `FAILED`, `KILLED`, or `FINISHED`. Ambiguous states such as `NOT_FOUND` keep the existing transport-error behavior.
   
   ### How was this patch tested?
   
   ```shell
   build/mvn test -pl kyuubi-server -am -Dtest=none \
     -DwildcardSuites=org.apache.kyuubi.operation.KyuubiOperationSuite
   
   build/mvn test -pl kyuubi-server -am -Dtest=none \
     -DwildcardSuites=org.apache.kyuubi.operation.KyuubiOperationPerConnectionSuite
   ```
   
   Both suites passed: 2/2 and 15/15 tests.
   
   Also ran `dev/reformat` and `git diff --check`.
