feat(PROJ-79): tailwindcss v3 -> v4 + tailwind-merge v3 Upgrade

Offizielles @tailwindcss/upgrade-Tool durchgelaufen: tailwind.config.ts entfernt, Theme nach globals.css als @theme-Block (CSS-first-Config), PostCSS auf @tailwindcss/postcss umgestellt. tailwind-merge im selben Schritt auf v3 (Pflicht-Kopplung an Tailwind v4). Codemod-Bug korrigiert: variant="outline" (Prop-Wert) wurde faelschlich als CSS-Klasse zu "outline-solid" umbenannt in 4 Call-Sites - zurueckgesetzt. Neue Lint-Regel (no-restricted-syntax) gegen *-opacity-* Utilities, die in v4 nicht mehr existieren und von tailwind-merge v3 lautlos verschluckt wuerden statt einen Fehler zu werfen. tsc/lint/build gruen. Visueller Regressionstest offen (kein Browser-Tool in dieser Session) - folgt auf 132 vor 131-Deploy.
