feat(t5): Beute-Bühne folgt Sonne und Darstellung live (T5a A12)

- useHoloTheme liest die --holo-*-Token nur bei einem Wechsel von
  Dunkel/Sonne neu (Attribut-Beobachter plus apicore:appearance), nie pro
  Bild; gleiche Token behalten das Theme, nur Farbmaterialien werden neu
  gebaut und alte freigegeben.
- Sonne nach Beute-Spec 9.3 und T5 17.8: schwarze Bühne ohne Boden,
  Spiegel, Bloom, Vignette, Dunst und Partikel; weiße Kanten 2 px in
  Bildschirmbreite (Hover, aktiver Platz, Vorschau 3 px), Rähmchen
  schwarz-weiß schraffiert, Labels 16 px auf fester Platte, neutrales Licht.
- Glas-Knöpfe ohne Blur und Schein in Sonne.
