Subject: [PATCH] Site Health: Use an integer value as a fallback in the
 available disk space check.

This avoids a few type problems further in the code: boolean divided by a number, or passing `false` to `size_format()` which is documented to accept integers or strings only.

Follow-up to [51815].
