Add a User Profile Details component for the user profile page

Problem/Motivation

Varbase Users Base 1.0.1 renders a "Profile details" card on a user's own profile page (#3630123), through the active theme's user-profile-details component. Vartheme BS5 5.0.6 added that component (#3630124). The Educare theme is a clone without it, and its user page prints its own Edit profile and Log out buttons, the picture and "Member for", which the card already carries, so the owner would see them twice.

Steps to reproduce

1. Install Educare 1.0.x-dev on Varbase 11 with Varbase Users Base 1.0.1.
2. Log in as a user with no extra role and visit /user.

Environment: Drupal 11.4.9, Varbase 11.0.x-dev, Vartheme BS5 Educare 1.0.x-dev, PHP 8.4, MariaDB 11.8 (DDEV).

Proposed resolution

• Add the organisms/user-profile-details SDC (noUi: true): a Bootstrap card with the picture (a bootstrap-icon person icon when there is none), a description list of the account details, and quick action buttons. Rows with no value are left out. Props: heading, username, full_name, email, timezone, status, created, member_for, last_login, picture_url, picture_alt, actions.
• In vartheme_bs5_educare_preprocess_user(), when the owner views their own profile and the card is present, skip the theme's own action buttons and drop the picture and "Member for" from the content. Administrators viewing someone else's profile are unchanged.
• The icon uses text-dark (the Educare navy), because the theme does not set $primary.
