fix(config): fix the issue where --es fails to start (#6757)

* fix(config): remove redundant JSON-RPC config fields and consolidate parameter binding

Remove maxBlockFilterNum, maxAddressSize, and maxRequestTimeout from NodeConfig/CommonParameter
since they were superseded by the jsonRpcMaxBatchSize/jsonRpcMaxResponseSize parameters.
Consolidate the config binding path so all JSON-RPC size limits flow through a single
reference.conf entry, and clean up stale test-config fixtures.

* fix bug of NodeConfigTest

* remove allowShieldedTransactionApi from reference.conf

* add testcase of external.ip is null

* change comment

* fix the bug of --es and 7 failed testcases
