lazy load assets and avoid push scripts

[tanthammar]

This PR does the same as #20 but also avoids @Push('scripts')

Why:

• alpine lazy load assets enables
  -- adding this form field to forms that are initially hidden
  -- avoids loading the script multiple times, if the field exists in multiple times on the same page
• @Push('scripts') is generally a bad idea for livewire components
