Renders a notification through shiny::showNotification(). The default
Shiny / bslib notification chrome (background, border, position, status
color, dismiss button) is used as-is; toast() only adds support for the
extra parameters below — header (title + optional icon), body, and
subtitle footnote — emitted as flat blocks so they do not produce a
card-in-notification (box-in-box) look. The type option in options
controls the status color via Shiny's own notification statuses
("default", "message", "warning", "error").
