feat(auth): enhance logo behavior and simplify billing logic (#11574)

Added default domain redirection functionality to the Logo component,
leveraging UndecoratedLink for navigation when default logos are used.
Removed metered product billing feature flag logic in the billing
webhook subscription service to simplify and streamline the codebase.
