chore: migrate server URLs from IP to bollwerk.online domain

Replace all HTTP references to 195.246.231.210 with bollwerk.online
across skills, prompts, scripts, and app default settings:

- Dockerfile: rename KRISENVORRAT_JWT_SECRET to BOLLWERK_JWT_SECRET
- SettingsKey.kt: default server URL now http://bollwerk.online:8080
- publish SKILL/prompt/script: HTTP URLs updated to bollwerk.online
- vps-deploy SKILL: Admin-UI and health-check URLs updated
- run-integration-tests.ps1: default BaseUrl updated

SSH commands (ssh/scp) intentionally kept on IP, as DNS is not
used for SSH access.
