[plan] One instance-type catalogue: allow-list managed from live AWS
_Automatically composed from the parent epic at dispatch time._
Outcome
Split by Architect seam into 7 coders, 4 phases: allow-list core + IAM → browse API, order guards, Products area → Instance types UI → hosting picker/stale. C5 moved to phase 2 per critic; dev checks deferred with local/live-AWS backstops.
