feat: Rich-Text-Editor, Bild-Skalierung, PDF-Fix & Zeichenlimit

Browse Source 
- Bild-Skalierung in Kartenansicht gefixt (object-position: top, 300px)
- Admin-Slider für Zeichenlimit (4–32.000) als Modul-Setting
- Textarea durch RichTextEditor (Quill.js) ersetzt
- PDF: HTML-Parsing, Einzelperson-Filter, Autorisierung für alle User

# PDF-Design: Modern Glassmorphism Layout
## Design-Konzept
Das PDF-Layout verwendet ein **modernes Glassmorphism-Design** — inspiriert von Apple Keynote-Slides und Behance Case Studies. Jede Seite besteht aus einem vollflächigen Hintergrundbild mit zwei **schwebenden Glass-Cards** (Titel oben, Beschreibung unten).
## Aufbau (Layer-System)
```
┌─────────────────────────────────┐
│ LAYER 1: Vollbild-Hintergrund │ ← Edge-to-Edge Bild
│ │
│ LAYER 2: Oberes Dark-Overlay │ ← Kontrast für Titelkarte
│ ┌───────────────────────────┐ │
│ │ ███ TITELKARTE (Glass) ███ │ ← Name + Jahr
│ └───────────────────────────┘ │
│ │
│ (Bild sichtbar) │
│ │
│ LAYER 3: Unteres Dark-Overlay │ ← Kontrast für Beschreibung
│ ┌───────────────────────────┐ │
│ │ ███ BESCHREIBUNG (Glass) ██ │ ← Bio-Text
│ └───────────────────────────┘ │
└─────────────────────────────────┘
```
## Glassmorphism-Technik (Build-Safe)
Jede Karte nutzt die `Decoration` API mit mehrfachen `.Before()` Layern:
```csharp
.Decoration(card =>
{
// 1. Weicher Schatten (sehr dezent, außen)
card.Before()
.Border(4f).BorderColor("#18000000")
.CornerRadius(20);
// 2. Lichtkante (innerer Glas-Rim)
card.Before()
.Border(1f).BorderColor("#44FFFFFF")
.CornerRadius(20);
// 3. Halbtransparenter dunkler Hintergrund
card.Before()
.Background("#C8181828")
.CornerRadius(20);
// 4. Inhalt (Text)
card.Content()
.PaddingVertical(28)
.PaddingHorizontal(36)
.Column(inner => { /* ... */ });
});
```
## Design-Details
| Element | Stil |
|---------|------|
| **Name** | 36pt, ExtraBold, Uppercase, Weiß, Letter-Spacing 0.5 |
| **Trennlinie** | 1.5pt, halbtransparent Weiß (#55FFFFFF) |
| **Jahrgang** | 15pt, gedämpft (#CCFFFFFF), Letter-Spacing 1.5 |
| **Beschreibungs-Header** | 14pt, SemiBold, gedämpft, Letter-Spacing 2 |
| **Beschreibungstext** | 11pt, 1.5 Zeilenhöhe, leicht gedämpft (#E8FFFFFF) |
| **Titelkarte Radius** | 20px |
| **Beschreibungskarte Radius** | 16px |
| **Overlay oben** | 220pt Höhe, #99000000 |
| **Overlay unten** | 280pt Höhe, #AA000000 |
| **Seiten-Padding** | 40pt rundum |
## Vorteile dieses Ansatzes
- ✅ **100% Build-Safe**: Keine SkiaSharp-Abhängigkeit, rein QuestPDF Fluent API
- ✅ **Stabil auf jedem Bild**: Kontrast-Overlays garantieren Lesbarkeit
- ✅ **Visuell hochwertig**: Glasskarte + Tiefe + Typografie-Hierarchie
- ✅ **Strukturell unverändert**: Name oben, Beschreibung unten, Bild vollflächig
