fix: placeholder picker improvements + insight display names (Issue #28)
Backend:
- get_placeholder_catalog(): grouped placeholders with descriptions
- Returns {category: [{key, description, example}]} format
- Categories: Profil, Körper, Ernährung, Training, Schlaf, Vitalwerte, Zeitraum
Frontend - Placeholder Picker:
- Grouped by category with visual separation
- Search/filter across keys and descriptions
- Hover effects for better UX
- Insert at cursor position (not at end)
- Shows: key + description + example value
- 'Keine Platzhalter gefunden' message when filtered
Frontend - Insight Display Names:
- InsightCard receives prompts array
- Finds matching prompt by scope/slug
- Shows prompt.display_name instead of hardcoded SLUG_LABELS
- History tab also shows display_name in group headers
- Fallback chain: display_name → SLUG_LABELS → scope
User-facing improvements:
✓ Platzhalter zeigen echte Daten statt Zahlen
✓ Durchsuchbar + filterbar
✓ Einfügen an Cursor-Position
✓ Insights zeigen custom Namen (z.B. '🍽️ Meine Ernährung')
