fix: disable MCP Apps that don't render in Claude.ai

Disable 3 MCP Apps (workflow-list, execution-history, health-dashboard)
that show as collapsed accordions and remove n8n_deploy_template tool
mapping that renders blank content. The server sets _meta correctly on
the wire but the Claude.ai host ignores it for these tools. Keep the 2
working apps (operation-result, validation-summary) active.

+- **MCP Apps: Disable non-rendering apps in Claude.ai**: Disabled 3 MCP Apps (workflow-list, execution-history, health-dashboard) that render as collapsed accordions in Claude.ai, and removed `n8n_deploy_template` tool mapping which renders blank content. The server sets `_meta` correctly on the wire but the Claude.ai host ignores it for these tools. The 2 working apps (operation-result for 6 tools, validation-summary for 3 tools) remain active. Disabled apps can be re-enabled once the host-side issue is resolved.
