[server] Validate Java version >= 11 in config.sh to prevent silent startup failures

[matrixsparse]

Summary

• Add is_jdk_version_ge_11() function in config.sh to validate Java version
• Insert version check after JAVA_RUN resolution, before any process startup
• When Java < 11, print clear error message and exit with code 1

Test Plan

• bash -n syntax check passes on config.sh, coordinator-server.sh, tablet-server.sh, local-cluster.sh
• Integration test: Java 17 correctly passes version check; simulated Java 8 correctly blocked with error message

Fixes #3192

@matrixsparse thank you for the fix, I have verified this fix works for me.

one minor comments, we already have is_jdk_version_ge_17 func in config.sh, should we merge these into one? cc @luoyuxia

@Yohahaha Thanks for the review! I've merged is_jdk_version_ge_11 and is_jdk_version_ge_17 into a single parameterized function is_jdk_version_ge(). PTAL again, thanks
