Rename ifcviewer-autodesk connector to bonsaiviewer-autodesk

Follows the host viewer's rename to Bonsai Viewer: directory, Python
package, entry point, PyInstaller spec, keyring service, and on-disk
config/cache paths all use the bonsaiviewer-autodesk name. CI workflow
filename and path filters updated to match.
