The browser installer creates user 1 as admin instead of the Varbase webmaster account

Problem/Motivation

When Varbase is installed through the browser installer, user 1 is created as admin and the email field starts empty. That is RecipeKit's default (Drupal\RecipeKit\Installer\Hooks::installConfigureFormAlter() hardcodes a hidden name element with the value admin).

Varbase sites are set up with a webmaster account — ddev install-varbase minimal|full already creates webmaster / webmaster@vardot.com — so the web installer is inconsistent with the documented Varbase account, and every browser-installed site ends up with a user named admin.

Steps to reproduce

1. Install Varbase through the browser installer (not ddev install-varbase).
2. Reach the "Create your account" step.
3. Observe the username is hidden/hardcoded to admin and the email field is empty.
4. Finish the install: user 1 is created as admin with no default email, unlike the webmaster account ddev install-varbase creates.

Proposed resolution

Override RecipeKit's defaults in the profile's hook_form_alter() for install_configure_form, so the browser installer creates the same account as ddev install-varbase:

  if ($form_id === 'install_configure_form') {
    $form['admin_account']['account']['name']['#default_value'] = 'webmaster';
    $form['admin_account']['account']['mail']['#default_value'] ??= '';
    if (empty($form['admin_account']['account']['mail']['#default_value'])) {
      $form['admin_account']['account']['mail']['#default_value'] = 'webmaster@vardot.com';
    }
  }

The email stays editable — it is only pre-filled with the Varbase default; whatever the installing user types wins.

Tested (Drupal 11.4, Varbase 11.0.x, DDEV, real browser, fresh install from a dropped database):

• The installer's "Create your account" step now pre-fills the email with webmaster@vardot.com, and the hidden username element carries webmaster instead of admin.
• After the install completes, user 1 is webmaster with webmaster@vardot.com, and system.site.mail is webmaster@vardot.com.
• Verified on the Varbase Starter site template (so this is not specific to any one template).

AI-Generated: Yes (Used Claude Code to implement and test this fix against a fresh Varbase 11.0.x install; reviewed by rajab-natshah.)
