Add application configuration prompt for already-optimized systems

- Add check for application configuration when system is already optimized
- Prompt user to configure apps even if tmpfs mounts already exist
- Create standalone configure-apps-for-tmpfs.sh script
- Detect if applications are already configured (Firefox prefs check)
- Skip redundant configuration attempts with 'already configured' messages
- Add backup timestamp to avoid overwriting previous backups
- Update README with new configuration script

Benefits:
- Users with existing tmpfs can now configure applications
- Standalone script allows re-configuration without full optimizer run
- Smarter detection prevents duplicate configurations
- Better user experience for incremental optimization
