[core] Fix delay on failed component being dropped; DRY the is_failed check

The is_failed() skip exists in two execution paths: the heap loop in call()
and should_skip_item_() (defer queue / delay:0). The previous commit only
exempted SELF_POINTER items from the heap-path check, so on multi-threaded
platforms a delay:0 continuation whose host component had failed would still
be silently dropped.

Extract a single is_item_failed_() helper (with the SELF_POINTER exemption)
and use it from both paths so they cannot drift again.

Add an integration test that schedules a delay from a component that marks
itself failed and asserts the continuation still fires (verified to fail
without the exemption).
