Show users their own account details on their profile page

Problem/Motivation

After logging in, a user lands on their profile page and sees little more than their name and "Member for". They cannot see their own account details: the email address it is registered with, the time zone dates are shown in, whether the account is active, when it was created or when they last logged in.

Core does not let Views show most of these to the account owner (email, time zone, status and last login are limited to user administrators), so this needs a small rendering layer rather than a view.

Steps to reproduce

1. Install Varbase 11.0.x.
2. Log in as a user with no extra role and visit /user.
3. Only the picture and "Member for" show.

Environment: Drupal 11.4.9, Varbase 11.0.x-dev, PHP 8.4, MariaDB 11.8 (DDEV).

Proposed resolution

Add a varbase_user_profile_details ECA model to the recipe:

• An ECA extra field, "Profile details", on the user display. It renders only for the account owner, varies by user, and can be moved or hidden on Manage display.
• An ECA block, "User profile details", for the logged-in user. Drupal Canvas offers it as a block component, for an account or dashboard page.
• Both render the active theme's user-profile-details SDC with: username, full name (only when the site has a field_full_name, or field_first_name and field_last_name), email, time zone, account status, account created, member for, last login, the user picture, and Edit profile / Change password / Log out actions. A theme without the component renders nothing.
• Only Drupal's default user fields are used: no field is added.
• The recipe installs eca, eca_base, eca_render, eca_user and modeler_api, and requires drupal/eca and drupal/modeler_api.
