v1.3.0: Refactoring Phase 3+4, Symbol-Verwaltung Redesign, Schlauch-Labels Fix

- Refactoring: Error Boundaries, apiFetch Wrapper, Socket Status-Tracking
- Refactoring: UI Kontrast (theme-aware colors), unused imports bereinigt
- Symbol-Verwaltung: Neues Split-Panel (Meine Symbole + Bibliothek)
- Symbol-Verwaltung: Umbenennen (TLF rot/blau), Duplikate erlaubt
- Symbol-Verwaltung: Karten-Sidebar zeigt eigene Symbole bevorzugt
- Schlauch-Labels: Groessere Schrift (13px/10px), verschiebbar (Drag)
- Schema: TenantSymbol customName, sortOrder, unique constraint entfernt
- Open Source Referenz entfernt (kostenloses Projekt)
