[ISSUE #10853] fix(store): validate HA state ordinals

[yuluo-yx]

Which Issue(s) This PR Fixes

• Fixes Auto-switch HA readers do not handle unknown state ordinals safely #10853

Brief Description

Adds bounds-checked HA state decoding. The server rejects unknown slave state ordinals and the client logs mismatched unknown master states without indexing outside the enum array. Adds boundary tests for state decoding.

How Did You Test This Change?

mise x java@temurin-17 -- mvn -Dmaven.repo.local=/private/tmp/rocketmq-m2 -pl store -am -DskipITs -Dtest=HAConnectionStateTest -Dsurefire.failIfNoSpecifiedTests=false test

The targeted tests, Checkstyle, and SpotBugs completed successfully.

Summary

The change correctly replaces unchecked HAConnectionState.values()[ordinal] lookups with a bounds-safe fromOrdinal helper, preventing ArrayIndexOutOfBoundsException on malformed HA state ordinals. However, the newly added test file contains a malformed annotation that will block compilation, so that must be fixed before merge. Additionally, the contributor CLA is unsigned, which must be resolved prior to approval.

Summary

The malformed test annotation from the previous review has been fixed. The fromOrdinal helper is correctly bounds-checked, server-side properly rejects unknown slave state ordinals, and client-side safely handles unknown master states via null return. Tests cover boundary cases adequately. LGTM.
