fix(tests): update electron tests for SettingsModal→SettingsPage rename and version sync

SettingsModal.tsx was renamed to SettingsPage.tsx (full-page view, not a modal
overlay) but test_electron_chat_app.js still referenced the old name, causing
ENOENT failures. Also syncs package.json version to 0.17.6 to match version.py.
