Subject: [PATCH] fix(specs): stamp per-service server on merged operations

generate-specs.mjs merged Core+MX specs but only set a document-level Core server, so MX endpoints rendered api.pay.walletconnect.com instead of api.merchant.pay.walletconnect.com. Tag each operation with its source service's server URL.
