fix: gracefully handle unknown fields in SSE optimistic record updates

When SSE events include custom fields not present in the client-side
object metadata (e.g. user-defined fields on Opportunity), the
computeOptimisticRecordFromInput function was throwing a fatal error
that broke the entire SSE event stream processing. Since the function's
for-loop already only processes known metadata fields, unknown fields in
the record input are naturally skipped. Replace the throw with a
console.warn so processing continues gracefully.
