Fix JNI parameter type in nativeReplaceImageByName causing SIGSEGV on armeabi-v7a

[CodeJhF]

问题

Java_org_libpag_PAGFile_nativeReplaceImageByName 的 imageObject 参数在 C++ 侧被声明为原生 long 类型，但 Java 侧声明为 long（对应 JNI 的 jlong，固定 64 位）。

在 armeabi-v7a（32 位 ABI）上，C++ 的 long 只有 32 位，与 JNI 期望的 64 位不匹配，导致传入的 nativeContext 指针被截断、参数错位，进而 reinterpret_cast 得到非法指针，触发 SIGSEGV 崩溃。64 位 ABI 下 long 恰好是 64 位，因此问题未暴露。

修改

将参数类型由 long 改为 jlong，与同文件中的 nativeReplaceImage 保持一致。

修复 #3590
