When a Python-based object throws an exception during the restoration
process (e.g. inside `onDocumentRestored`), the error is caught by a
generic `catch(...)` block in `Document::afterRestore`.
Previously, this block swallowed the C++ exception wrapper but failed to
clear the underlying Python error state. Leaving the interpreter in this
"dirty" state caused a segmentation fault or `SystemError` later in the
loading process when C++ attempted to interact with the Python API
(specifically in `App::Application::setActiveDocument`).
This commit adds a check for `PyErr_Occurred()` inside the catch block.
If an error is detected, the traceback is printed to the console for
debugging, and `PyErr_Clear()` is called to reset the interpreter state,
allowing the application to continue loading the document without
crashing.
* #25474 Added read-only warnings when saving documents
Block saving a file and notify user if windows is unable to save to the file for any reason, or the read-only attribute is checked. Also check std::filesystem::perms for write permission and other checks in FileInfo::isWritable(), although it doesn't seem to matter on windows.

Assigning a material without an appearance reset the appearance to the
default appearance.
There were two main problems. One was the comparison function for
App::Material objects. It would return false when the UUID or MatType
values were different although there are many circumstances where this
could be true and the appearance be the same. It also incorrectly
compared the imagePath.
The second problem was the logic for detecting if an object has already
been assigned an appearance by assigning a material or manually setting
the appearance. If assigned a material, the appearance should update but
not if it has been set manually. This logic has been corrected.
