feat(templates): nom d'agent par défaut + permissions système et MCP outils sur AgentTemplate — #242

AgentTemplate étendu (defaultAgentName, systemPermissions, mcpToolPermissions),
CreateTemplate/UpdateTemplate/CreateAgentFromTemplate projetés vers l'agent créé,
DTO/MCP tools et persistance store complétés. Correctif modèle par défaut:
UpdateTemplate ne persistait pas defaultProfileId (profil stale à la création
d'agent). Backfill best-effort des templates existants depuis les agents du
projet au open_project, overrides explicites uniquement.
