Throw typed exception for Parquet footer error

### Describe the enhancement requested

Currently, `ParquetFileReader` throws `RuntimeExceptions` when footer parsing fails.

This can be improved by throwing a `ParquetDecodingException` when footer parsing fails, so footer corruption surfaces as a typed exception instead of a plain `RuntimeException`. This helps avoid matching on error message to catch errors occurred during footer parsing.

### Component(s)

_No response_

从 ParquetFileReader 开始，结合 ParquetDecodingException 检查 footer 解析的失败路径。确认损坏的 footer 导致的失败会以类型化异常而不是 RuntimeException 的形式向上层暴露，然后使用 repository 中现有的测试验证相关 reader 行为。
