UseInputStatusIcon

Builds the on-field status affordance for a bordered input and its accessibility wiring, so every input in the family behaves the same for a given status. The attached variant renders a plain glyph and leaves the text to the message box; the detached variant renders nothing here, because the message box already carries its own icon; the tooltip variant renders a real focusable button whose tooltip is reachable by keyboard, pointer, touch and assistive tech. Use it when building a bordered input, not for field-level messaging.
