…from source wxPython 4.3.0 was just published to PyPI with no Linux wheels at all (macOS/Windows only). requirements.txt pinned wxPython with no upper bound, so pip picked 4.3.0 as the newest match, found no wheel on extras.wxpython.org (which still tops out at 4.2.5 there) or PyPI, and fell back to building wxWidgets from source in the AppImage job, which only installs runtime GTK/X11 libraries and fails without the gtk+-3.0/libcurl dev headers a source build needs. Since wxPython is being phased out in favour of Qt and is only needed by the not-yet-ported legacy wx_* modules, pin it to 4.2.5 (already the version pytest.yml pins independently) instead of chasing extras.wxpython.org's build lag on every future release. Also add --only-binary wxpython to build-appimage.sh and the Flatpak python-wxPython module so a future drift fails fast with a clear pip error instead of silently attempting a doomed source build.
Anticipates the reasonable-looking but wrong fix of matching the wheel to the CI runner's Ubuntu version: flatpak-builder builds this module sandboxed inside org.freedesktop.Platform//25.08, not the raw host, so the runner's own Ubuntu version is irrelevant to the wheel's ABI. The ubuntu-22.04 pin is tied to hand-extracted libjpeg8/libtiff5/libjbig0/ libdeflate0 shim modules from issue #232; swapping wheel versions needs those shims reworked and re-verified on real hardware, not just a URL edit.

Summary
requirements.txt's unboundedwxPython >= 4.2.2, found no wheel anywhere for Linux, and fell back to building wxWidgets from source, which fails since the AppImage job only installs runtime GTK/X11 libraries, not thegtk+-3.0/libcurldev headers a source build needs.wxPython==4.2.5inrequirements.txt(matching whatpytest.ymlalready pins independently) and in the Flatpak manifest'spython-wxPythonmodule, since wxPython is being phased out for Qt anyway and doesn't need to track every upstream release.--only-binary wxpythontobuild-appimage.shand the Flatpak module so a future version drift fails fast with a clear pip error instead of silently attempting a doomed multi-minute source build.python-wxPythonmodule deliberately stays on theubuntu-22.04extras.wxpython.org wheel rather thanubuntu-24.04, even though the CI runner itself is 24.04:flatpak-builderbuilds that module sandboxed insideorg.freedesktop.Platform//25.08, not the raw host, and the 22.04 wheel's ABI is what the hand-builtlibjpeg8/libtiff5/libjbig0/libdeflate0shim modules (issue Is there any plan for flatpak or appImage version? #232) are matched to.Fixes #962.
