fix(scripts): keep the weekly price sync alive past unrepresentable rows

Vercel now lists video and embedding models without token pricing or token
limits, and the first of them KeyError'd the whole weekly run before any
provider was synced. Those rows are skipped, and a failed catalog fetch for
any provider now yields an empty transform instead of a crash.
