Fix Webpack build errors in Legit.service.Legit using webpackIgnore

The apps/legit/service/Legit.mjs service uses dynamic imports for external modules (from esm.sh) to keep the initial bundle size low.

const {openLegitFs} = await import('https://esm.sh/@legit-sdk/core');
const fsModule      = await import('https://esm.sh/memfs');

Webpack attempts to resolve these URLs as local modules or npm packages during the build process, causing the npm run build-all command to fail with: Error: The target environment doesn't support dynamic import() syntax so it's not possible to use external type 'module' within a script

Goal: Prevent Webpack from attempting to process these specific import statements so they are handled natively by the browser at runtime.

Task: Modify apps/legit/service/Legit.mjs to add /* webpackIgnore: true */ comments to the dynamic imports.

const {openLegitFs} = await import(/* webpackIgnore: true */ 'https://esm.sh/@legit-sdk/core');
const fsModule      = await import(/* webpackIgnore: true */ 'https://esm.sh/memfs');

This should resolve the build errors while maintaining the dynamic loading functionality in the browser.
