feat: migrate to Module Federation 2.0

Replace the moduleEntry.ts (which combined defineModule + window.__NKZ__.register)
with a clean src/Module.tsx that exports defineModule({...}) only. The
@nekazari/module-builder@2.0.0 preset wires it as a federated remote.

- Lazy-load components/MainView as main.
- Extract i18n bundle registration into src/i18n.ts.
- Add nkz.moduleId (id remains 'nkz-module-eu-elevation' for marketplace_modules
  compatibility) and drop obsolete preset options.
