[Fix] 0045422: Use ButtonContextRenderer for Glyph in Filter and Mode…

[fhelfer]

Error: The element “a” must not appear as a descendant of the “button” element.

Glyphs with action were rendered as and ended up inside ,
which is invalid. Extend USE_BUTTON_CONTEXT_RENDERER_FOR with
StandardFilterContainerInput and ModeViewControl so glyphs render
as in these contexts.

Problem

• Validator: <a> als Nachfahre von <button> ungültig (z. B. Filter, Dashboard ViewControlMode).

Lösung

• GlyphRendererFactory: StandardFilterContainerInput und ModeViewControl zu USE_BUTTON_CONTEXT_RENDERER_FOR hinzufügen → Glyphe als span in diesen Kontexten.
