ci(checkpoint): gate TRTLLM DynamoCheckpoint tests on snapshot changes only

Follow the vLLM/SGLang pattern from #11046 (ci: gate DynamoCheckpoint
deploy tests on snapshot changes only): narrow the changed-files gate on
every TRTLLM checkpoint job (snapshot-placeholder, operator setup,
snapshot-agent, deploy-test, cleanup) from (operator || snapshot ||
deploy) to (snapshot == 'true'). Also drop the redundant operator.result
== 'skipped' branch so the operator-setup gate matches vLLM/SGLang.

The snapshot path filter (.github/filters.yaml) already covers
tests/deploy/test_dynamocheckpoint.py, so TRTLLM test changes still
trigger these jobs. post-merge-ci.yml already gates all three frameworks
identically and needs no change.
