Krea removed the batchSize parameter ("Generation batch size is no longer
supported, submit one request per output"), so every image request failed
with HTTP 422 — breaking session/agent avatar generation. Drop batchSize
from the payload and instead send one request per requested image in a
loop, collecting all returned jobs. Endpoint paths, Bearer auth and base
URL are unchanged.
- KreaService: remove batchSize from payload
- KreaService: loop record.BatchSize times, one POST per image, aggregate
jobs (handles both array and single-object responses)
