Implement user-configurable settings with enhanced UI

Configuration Changes:
- Store config.ini in platform-specific user directories
  - macOS: ~/Library/Application Support/MSMD/
  - Windows: %APPDATA%\MSMD\
  - Linux: ~/.config/MSMD/
- Automatically create default config on first run
- Config file now editable and persists across app updates

Settings Dialog Enhancements:
- Add "Show Reference Creator" checkbox to Settings UI
- All settings now configurable through UI (no manual editing required)
- Settings dialog dynamically updates reference creator button visibility

Technical Implementation:
- Add getUserConfigDir(), getConfigFilePath(), createDefaultConfig() helper functions
- Update readConfig() and writeConfig() to use user config location
- Enhanced Settings.py with QCheckBox for showReferenceCreator
- Automatic config migration from old location (if exists)

Documentation:
- Update README with config file locations
- Document both UI and manual configuration methods
- Update troubleshooting section

This resolves the bundled app config.ini issue - config is now user-writable and survives app updates.
