The new Workload Identity workflow for Vault tokens correctly handles post-stop tasks, however the legacy workflow does not. Attempts to get a Vault token are rejected if the allocation is server-terminal or client-terminal, but we should be waiting until the allocation is client-terminal (only) so that poststop tasks get a chance to get Vault tokens too.
Fixes: #16886
See #16886 (comment) for testing details.
