test(tvix/store/signing_wrapper): restructure r/8790

Move things around a bit to make it easier to understand what's going on:

 - We first validate our fixture invariants
 - We then insert into the PathInfoService
 - Do all comparisons and checks we can on the returned PathInfo struct
 - Only convert to the NarInfo variant to calculate the fingerprint,
   and don't keep intermediate let bindings for this

Before cl/12588, this was arguably much harder to do that way, as we
relied on some of the conversions done in the to_narinfo() function.
