[Bug]: Connection validation rejects bracketed IPv6 endpoints #4413
Description
What happened?
A reachable bracketed IPv6 endpoint fails before connection validation because splitting on colons loses its host and port. CommonUtil.telnetOrPing throws IllegalArgumentException; the existing KafkaClusterSimpleInfo.validate bean uses that helper and also fails.
Expected: reachable bracketed IPv6 endpoints pass, while IPv4, optional chroot, fallback and malformed-port rejection remain supported.

How to reproduce
- Open a loopback ServerSocket on ::1 with an ephemeral port p.
- Call CommonUtil.telnetOrPing("[::1]:" + p). The current split attempts to parse an empty token as the port and throws before connecting.
- Set the same endpoint as brokerList on KafkaClusterSimpleInfo and call validate; it also fails.
- Repeat with /service appended to the endpoint to exercise the optional chroot.
Relevant log output
Anything else
Tests exercise real IPv4/IPv6 ServerSockets and the production helper/bean. Four of six initial cases fail on the base. Seven final cases pass, including the review-discovered empty-port regression; all 15 reactor modules compile and Spotless/Checkstyle pass. No deployed Kafka registration flow was exercised. A tested fix is ready in hutiefang76/amoro branch fix/kafka-ipv6-address-validation.
