Update AI Prompt System and Admin API

- Incremented version to 1.1 and updated the status to reflect the implementation of core features including `ai_prompts`, `prompt_resolver`, and the Superadmin HTTP API.
- Documented the current API endpoints for managing AI prompts, including CRUD operations and preview functionality.
- Introduced a new placeholder catalog and preview capabilities for the Superadmin interface.
- Enhanced the backend with new functions for handling AI prompt templates and integrated them into the API.
- Updated frontend components to include navigation and routing for the new Admin AI Prompts page.
- Incremented application version to 0.8.158 and updated changelog to reflect these changes.

-**Status:** DRAFT
+## 8. Prompt-Kaskaden (geplant — nicht implementiert)
+
+**Ziel:** Vorlagen, die andere Prompts einbinden oder in feste Stufen (System → Fach → Ausgabeformat) zerlegt werden — ohne die DB-Templates mit duplizierten Fliesstexten zu zersplittern.
+
+**Konzeptskizze:**
+- Optional neues Feld `base_slug` oder eigene Tabelle `ai_prompt_composition` (Reihenfolge, Rolle: `system|user|prepend`).
+- Platzhaltersyntax z. B. `{{include_prompt:slug}}` mit **maximaler Verschachtelungstiefe** und Zykluserkennung.
+- Auflösungsreihenfolge: (1) eingebundene Slugs expandieren, (2) Kontext-Variablen wie heute ersetzen.
+
+Bis zur Umsetzung bleiben zusammengesetzte Anweisungen im **einen** Template pro Slug (wie `exercise_skill_suggestions` mit `{{skills_catalog}}`).
+
+---
+
+**Version:** 1.1  
+**Datum:** 2026-05-30  
+**Status:** Teile umgesetzt (DB 067/069, Resolver, Superadmin-API + UI); Kaskaden offen
