praisonai-platform: Any workspace member can delete the entire workspace via DELETE /workspaces/{id}

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling destructive action. The `DELETE /workspaces/{workspace_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member of the workspace can issue a single DELETE to wipe the entire workspace, including every project, issue, comment, agent, label, and member record (cascading via the foreign-key relationships). There is no owner-role gate, no confirmation token, no soft-delete window, no recovery path. PraisonAI Platform version 0.1.4 patches the issue.
