HanifKoh 41eeaf3883 Sanitize Server-Supplied Download File Names (#15955)
* Sanitize Server-Supplied Download File Names

The URL downloader used the file name from the Content-Disposition header
as given, without the cleaning and unused-name search applied to the
URL-derived name.

Reduce the header name to a sanitized base name with the new
sanitize_file_basename helper, which splits on both path separators and
rejects names made only of dots and spaces. Run the result through the
same unused-name search as the URL-derived name, now shared in
find_unused_filename, and fall back to the URL-derived name when nothing
usable remains.

* Sanitize Download Names Before Choosing an Unused One

The unused-name search probed the name as given and sanitized the
result afterwards, so a name whose special characters are replaced
could be mapped onto a file that already exists.

Move the search into libslic3r as find_unused_filename, sanitize first
and probe the name that is actually written. The download marker path
is shared through download_marker_path. Restore the last tried name in
the error reported when no free name is found, and cover the search
with unit tests.

* Keep Downloads on an Unused Name Until They Complete

When the server supplied the name, the download marker stayed under the
URL-derived name, so the adopted name was not reserved against other
downloads. The final rename also replaced any file that took the name
while the download ran.

Move the marker to the adopted name before any data is written, and
check the name again right before the final rename, picking the next
free name if it is taken by then.

* Sanitize the File Name of Model Import Links

The model import took the file name from the link as given and only
avoided an existing file with a substring match on the folder listing.

Reduce the name to a sanitized base name, falling back to untitled.3mf,
choose the name with the shared unused-name search, and check it again
before the final rename.

* Handle Filesystem Errors When Finishing a Model Import Download

Choosing the final name and moving the downloaded project into place
could throw from inside the download callback. Any such error now removes
the temporary file and reports the existing import failure message.

Kris Austin efc9f253ee fix: resolve relative input paths given on the command line (#14803)
Opening a model with a relative path, for example `orca-slicer ./some.3mf`,
failed with "Loading of a model file failed." and "The file does not contain
any geometry data.", while the same file opened by an absolute path or by
drag and drop worked.

GUI_App::init_app_config() changes the working directory to <data_dir>/log,
and it runs from the GUI_App constructor because the app config is needed
early for instance checking. The input files are opened much later, in
post_init(), so a path still relative at that point resolved against the log
directory instead of the directory OrcaSlicer was started from, and the 3MF
reader failed to open it.

Resolve the input paths in CLI::setup(), which runs before GUI_App is
constructed and therefore before the working directory moves. Absolute paths
are returned unchanged, so the forms that open today are unaffected, and
custom open protocol URLs are passed through since post_init() hands those to
the downloader rather than the file loader.

The working directory change is left alone. It was added in #3248 so the TUTK
logs land in the data directory instead of the working directory (#3209).

Kris Austin fa3dbfcc6f fix: clear 1 warning - report the real error when a Windows G-code export fails (#15582)
fix: report the real error when a Windows G-code export fails

copy_file built its failure message as "Error: " + errCode. Adding a DWORD
to a string literal is pointer arithmetic, not concatenation, so the pointer
lands errCode bytes into an 8-byte literal and runs past its end for any code
above 7. std::string then calls strlen on it and throws length_error, and the
catch(...) in BackgroundSlicingProcess::finalize_gcode replaces the diagnosis
with "Unknown error occurred during exporting G-code."

Every code a user is likely to hit is past the end: write-protected media is
19, no media 21, a full disk 112, and a destination held open by another
program 32. Codes 1 to 7 stay inside the literal and produce a truncated
message instead. So the "Maybe the SD card is write locked?" text has not
been reachable on Windows since this path was added in #2923.

Now that it is reachable, that guess only fits removable media, so it is
conditional on m_export_path_on_removable_media. The existing string is
untouched and keeps its 23 translations; the fixed-drive case adds one string.

raistlin7447 2860353b9f fix: multi-user slicing crash on shared temp dir (#14607)
On Linux every account shares /tmp, but slicing builds temp paths there under
fixed, app-owned names via temporary_dir() (model backups, STEP import,
part-skip). The first user to slice creates and owns those dirs, so the next
user cannot write under them and slicing crashes with "No such file or
directory".

Tag the app temp root with the user id at startup (<temp>/orcaslicer_<uid>)
so every temporary_dir() consumer is isolated at once. The id stays at the
top level of the world-writable system temp so each user's dir is created
directly there; a shared parent dir would be owned by whichever user made it
first. The root is pre-created because STEP import writes into it directly.
Windows keeps the plain temp dir since it is already per-user.

Fixes #10108. Same root cause as #5969.
