test(lint): read the files these tests write without the session cache

Both new tests read a file their own run has just written, which the uncached-read lint flags because utils.cache.files.read_text is an lru_cache with no mtime invalidation. The two cases want different answers. The rendered inventory is YAML, so load_yaml_any reads and parses it the way the lint asks and needs no exception at all. The healthcheck probe writes its request through bash inside the test, so a cached read would compare against the previous run's bytes and the assertion would pass without proving anything; that one keeps a cache-read directive naming why.

make test-lint went from 2 failed to green, and the first attempt is the reason the inventory test carries no directive: suppressing the read there only moved the complaint to yaml.safe_load, which the right reader answers in one call.
