Pull Request Overview

This PR introduces a shared _user-image partial to render either an uploaded profile image or a generated SVG of user initials, updates the User model and controller to support nullable images, and refines related views and CSS for a consistent layout.

• Added InitialsImageGenerator to produce SVG data URIs for initials-based fallback images.
• Refactored profile.php, index.php, and sidebar.php to use the new _user-image partial.
• Updated the User model, panel controllers, and SCSS to handle nullable images and adjust flex layouts.

• This new InitialsImageGenerator contains public logic that would benefit from unit tests to ensure SVG generation, caching, and color contrast behave as expected.

The partial does not provide a default CSS class for the <img> element, which may break existing styling. Consider defaulting to 'user-image' when no class is provided.

Suggested change

	'class' => $class ?? null,
	'class' => $class ?? 'user-image',

[Copilot]

When inserting the image partial here, you may need to pass a CSS class (e.g., 'user-image') to maintain consistent styling with your existing SCSS rules.

[Copilot]

Same as above: pass a default class to the image partial here so the sidebar avatar matches your .user-image styling.

Suggested change

	<?= $this->insert('_user-image', ['user' => $panel->user()]) ?>
	<?= $this->insert('_user-image', ['user' => $panel->user(), 'class' => 'user-image']) ?>
