Prune old image generations after each prod deploy

Each promotion pulls a uniquely SHA-tagged image, so without cleanup old generations accumulate indefinitely. CT111's disk is small (was 5.9GB, just grown to 8.8GB) and filled up mid-pull on the first real promotion attempt. Prune dangling images after up -d swaps traffic to the new containers, once their predecessors are no longer referenced.
