refactor(ui): --pill-radius CSS-Variable (Item F)
border-radius: 999px war 15x im CSS dupliziert. Ausgelagert als
:root --pill-radius Variable im globalen :root-Block in +layout.svelte,
Call-Sites auf var(--pill-radius) umgestellt.

Bewusst NICHT angefasst (plan war "nur Werte die mehrfach vorkommen"):
- z-index: 10 Distinct Values in 14 Sites, bilden ein implizites
  Layer-System. Konsolidieren = behavior-change-Risiko ohne konkreten
  Nutzen. Wenn kuenftig einheitliche Modal-/Popover-Layer noetig,
  separate Phase.
- setTimeout(): 3 Sites, jeder mit eigener Semantik (Debounce/Print/
  Spinner). Kein DRY-Nutzen durch Extraktion.

Gate: svelte-check 0 Warnings, 184/184 Tests, Build clean, kein
sichtbarer Unterschied (einzige Aenderung: selber Wert ueber Variable).
