Site Branding and Logo Configuration

[yuanzui-cf]

Objective

Use the configured site logo consistently across authentication pages, application navigation, and browser branding.

Acceptance Criteria

• The logo URL is stored in system settings alongside the site name.
• Basic Settings edits the site name, logo URL, Console URL, and Public URL together.
• Login, Signup, and the application sidebar use the configured logo.
• Authentication pages display the logo directly without an additional background container and preserve its aspect ratio.
• The configured logo is also used as the browser favicon.
• Missing or failed logo images fall back to the default icon.
• Backend validation, public configuration, and Console behavior have regression coverage.
