ResourceManager: Master-Detail-Editoren fuer Schraffur- und Linien-Typen

Schraffuren- und Linien-Tab im Master-Detail-Layout (DOSSIER-Vorbild): Liste
links mit Live-SVG-Thumbnail + Name, Detail rechts mit grosser Live-Vorschau,
Inline-Rename, Trash-Delete, Typ-Umschalter. Schraffur: Vektor (parallel/
zufaellig) oder Bild (Upload -> Data-URL, scaleX/scaleY/rotation); kein
Farbfeld mehr (Farbe kommt von Bauteil/Attribut). Linie: Strich oder Zickzack
(Amplitude/Wellenlaenge). Bauteil-Tabelle: Vordergrund + Hintergrund statt
einer Farbe. Neuer eigenstaendiger Vorschau-Helfer ui/hatchPreview.tsx (kein
Renderer-Import).
