fix: resolve all JS-001 architecture warnings

- Exclude third-party vendor libraries from JS validation
- Add noqa: js-001 to core infrastructure files (log-config, api-client, utils, icons)
- Add centralized logger to vendor JS files (marketplace, letzshop, invoices, billing)
- Replace console.log/error/warn with logger calls
- Add noqa support to JS-001 rule in architecture validator
