Fix Java client time column access throwing ArrayIndexOutOfBoundsException for non-long typed getters

从 IoTDBRpcDataSet.java 开始，检查受影响的六个 ByTsBlockColumnIndex getter 方法，以及 getLongByTsBlockColumnIndex 和 getStringByTsBlockColumnIndex。验证树模型的时间列路径，然后在可用时运行相关的 Java 客户端测试；完成的标准是，所有列出的非 long getter 都报告明确的 StatementExecutionException，而不是访问列 -1。

Describe the bug and provide the minimal reproduce step

In IoTDBRpcDataSet.java, several ByTsBlockColumnIndex getter methods do not handle the tsBlockColumnIndex < 0 case (time pseudo-column in tree model). Only getLongByTsBlockColumnIndex and getStringByTsBlockColumnIndex correctly handle this case.

When tree model is used, column index 1 maps to tsBlockColumnIndex = -1 (time column). Accessing it through typed getters other than getLong or getString causes ArrayIndexOutOfBoundsException from TsBlock.getColumn(-1).

Affected methods:

• getBooleanByTsBlockColumnIndex
• getIntByTsBlockColumnIndex
• getFloatByTsBlockColumnIndex
• getDoubleByTsBlockColumnIndex
• getBinaryByTsBlockColumnIndex
• getObjectByTsBlockColumnIndex

This is the Java equivalent of the C++ client bug fixed in #17400.

What did you expect to see?

A clear StatementExecutionException with message like "Cannot read boolean from time column" instead of an opaque ArrayIndexOutOfBoundsException.

What did you see instead?

ArrayIndexOutOfBoundsException with index -1.

Anything else?
