✨ Add Super-Admin tools for managing any model

- 🛠️ Introduced generic Super-Admin MCP tools, including `list-models`, `describe-model`, `list-records`, `show-record`, `create-record`, and `update-record`.
- 🛡️ Restricted modification of critical fields (e.g., passwords, roles, tokens) to enhance security.
- ✅ Added extensive feature tests for Super-Admin functionality and access control.
- 📜 Increased pagination length to accommodate new tools on a single page.
- 🔗 Registered Super-Admin tools in `EinundzwanzigServer`.
