Upgrade to Core 2.0: Livewire admin + reCAPTCHA v2 checkbox

• Migrate admin screen to TailAdmin/Livewire (AdminLivewire via ConfigForm),
  remove legacy AdminLTE AdminController + Views/Admin.blade.php; admin route
  now points to the Livewire component.
• render.blade.php: switch the front widget from the ID-dependent invisible
  button (gp247-form-process / gp247-button-process) to the standard reCAPTCHA
  v2 checkbox. It self-injects g-recaptcha-response into the enclosing ,
  so it no longer depends on element ids the new GP247Front template dropped.
• AppConfig::disable(): use gp247_language_render for the error message.
• gp247.json: requireCore ["2.0"] + requireUpdateFrom.
• readme: rewrite to 247-doc format (VI + EN), correct v3 -> v2 checkbox,
  document operating conditions and Google reCAPTCHA v2 registration.
