fix(review): adopt latest server_rev on PUT; retry once on 409

Review was POSTing price/sku to /review before each save; that endpoint
persists those overrides and bumps server_rev, so the following PUT sent
a stale client_rev and hit 409 — Continue to Publish stayed disabled.
Stop sending price/sku on review probes (PUT already persists them) and
have updateSlab refetch + retry once on revision_conflict.
