docs(review): one status table at the top, and the float noted only there

Screenshots/README.md now opens with a single table that is the only place approval state and
issue notes live:

  | # | Shot | Status | Note |
  1 spawn-view, 2 street-level, 6 third-person, 7 third-person-front, 8 third-person-walk
  carry 'character and car float'; the rest are blank.

Everything else that duplicated that information is gone: the per-shot Verified/Approved
bullets, the warning block at the top, the prose in the known-issues section, and the second
signoff table the comparison generator used to append. Every image is marked pending, because
every image changed and each needs a fresh approval.

The comparison section keeps its side-by-side image table and points at the status table for
approval, so there is one place to sign off and one place to read what is wrong.
