Add or switch playbook(s) in a running crisis

Enable room creators to switch playbooks before tasks are started, addressing initial selection errors. Allow managers/administrators to add supplementary playbooks as crises evolve, expanding response capabilities. Implement clear visual differentiation between multiple active playbooks and prevent duplicate tasks through automated detection. This enhancement provides flexibility during crisis management without losing context, letting teams adapt their response strategy as situations develop. Include confirmation dialogs to prevent accidental changes and maintain a complete audit trail of playbook modifications for compliance purposes.
