feat(schematic): Terminal-Farben, Leitungen hinter Blöcken, Zeichenmodus v11.0

Terminal-Farben nach Verbindung:
- Terminals zeigen Farbe der angeschlossenen Leitung
- Grau = keine Verbindung, farbig = Leitung angeschlossen
- Neue Hilfsfunktion getTerminalConnectionColor()

Leitungen hinter Blöcken:
- Layer-Reihenfolge geändert: connections vor blocks
- Professionelleres Erscheinungsbild

Zeichenmodus-Verbesserungen:
- Rechtsklick/Escape bricht nur Linie ab, nicht Modus
- Crosshair-Cursor überall im SVG während Zeichenmodus
- 30px Hit-Area für bessere Klickbarkeit

 # CHANGELOG MODULE KUNDENKARTE FOR [DOLIBARR ERP CRM](https://www.dolibarr.org)
 
+## 11.0 (2026-03)
+
+### Neue Features
+
+- **Terminal-Farben nach Verbindung**: Terminals zeigen die Farbe der angeschlossenen Leitung
+  - Grau = keine Verbindung, farbig = Leitung angeschlossen
+  - Farbe entspricht dem Leitungstyp (L1=braun, L2=schwarz, L3=grau, N=blau, PE=gruen)
+  - Neue Hilfsfunktion `getTerminalConnectionColor()`
+
+- **Leitungen hinter Bloecken**: Wires werden nun hinter den Equipment-Bloecken gerendert
+  - Layer-Reihenfolge geaendert: connections-layer vor blocks-layer
+  - Leitungen "verschwinden" hinter Bloecken und kommen auf der anderen Seite wieder raus
+  - Professionelleres Erscheinungsbild wie in echten Schaltplan-Editoren
+
+### Verbesserungen
+
+- **Zeichenmodus-Verhalten**: Konsistentes Verhalten im manuellen Zeichenmodus
+  - Rechtsklick bricht nur aktuelle Linie ab, nicht den Zeichenmodus
+  - Escape-Taste verhaelt sich identisch (Linie abbrechen, Modus bleibt aktiv)
+  - Crosshair-Cursor ueberall im SVG waehrend Zeichenmodus (nicht nur auf Terminals)
+  - Keine Unterbrechung mehr beim Klicken auf leere Flaechen
+
+- **Terminal Hit-Area**: Verbesserte Klickbarkeit der Terminals
+  - 30px Radius fuer einfacheres Anklicken
+  - `pointer-events:all` fuer zuverlaessige Event-Erfassung
+
+### Bugfixes
+
+- Cursor zeigte nicht ueberall Crosshair im Zeichenmodus
+- Zeichenmodus wurde bei Rechtsklick/Escape komplett beendet statt nur Linie abzubrechen
+- Junction-Verbindungen (Terminal zu Leitung) werden korrekt gerendert
+
+---
+
 ## 8.6 (2026-03)
