Name the unreadable report's file, tighten the number and region checks

The corrupt-report arm names its file with wording distinct from the
backstop, so tests can tell them apart (and now do, plus the non-UTF-8
half). _is_number rejects bool and non-finite floats, and the RAM
region selects by key presence, so a falsy-but-present DRAM value is
malformed rather than absent -- the size report is the one input
nothing upstream validates, so these stay hardened. The not-app_size
comment carries the zero case it also swallows.
