Pull request overview

Updates pdf2htmlEX’s Poppler integration to build against Poppler 26.05.0, primarily by adapting to Poppler API/ABI changes in matrix/string handling, font APIs, and background renderers, plus minor CI/build script updates.

Changes:

• Updated multiple renderer/code paths to use newer Poppler types/APIs (e.g., std::array::data(), GooString string accessors, WritingMode enum, updated stream APIs, and updated glyph/CID mapping APIs).
• Adjusted background renderers (Splash/Cairo) for Poppler signature/enum changes and improved ownership semantics in proof rendering.
• Updated build configuration and automation (CMake module paths, GLib pkg-config checks, workflow runner version, and build scripts); removed legacy Travis CI config.
