site: show declared entrants as n/a rows; credit MattJackson on busbar

Reverse the 'unmeasured gateway is not a row' rule per owner policy: a declared
entrant (e.g. higress between merge and its first field run) now appears immediately,
n/a on every lane with version+contributor from its manifest, and fills with numbers
the moment its snapshot lands. Update the test that pinned the old exclusion to pin the
new inclusion (ghost row present, null measured_at, no fabricated matrix). Add
MattJackson as busbar's contributor.
