Extract duplicate static handler configuration logic from
registerStaticHandlersWithLocationEngine and registerStaticHandlers
into a new configureStaticHandler method.
- Create configureStaticHandler() to handle alias, cache, gzip,
symlink, internal, expires, and autoIndex configuration
- Both registration functions now call the shared configuration method
- Registration logic remains separate (LocationEngine vs Router)
