Restore intermediate cert + reduce IKE fragment size to 512 bytes
iOS/Android VPN stacks don't follow AIA to download intermediate certs,
so YE1 must be sent by the server for cert chain validation.
The original 1236-byte IKE fragment was being dropped mid-path.
Setting fragment_size=512 splits the 1776-byte IKE_AUTH into ~4
fragments of ≤560 bytes each, which should traverse any NAT/router.
