Add reconfiguration options for existing PBS installations
When PBS client is already installed, the script now offers: - Reconfigure connection only (server/credentials) - quick option - Full reconfiguration (all settings) - Reinstall PBS client and reconfigure - Exit without changes The connection-only reconfiguration preserves all backup settings (paths, schedules, retention) and only updates PBS server details and credentials. This is useful when switching backup servers or updating authentication tokens. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
