fix(config) : disable uninstalled McpBundle to fix boot crash

McpBundle was registered but symfony/ai-mcp-bundle is not installed,
causing a critical error on boot. Disabled all MCP references:
- bundles.php: removed McpBundle
- mcp.yaml: renamed to mcp.yaml.disabled
- routes.yaml: removed mcp route
- services.yaml: commented McpHeaderAuthenticator, excluded src/Mcp/
- security.yaml: commented mcp firewall and access control
- phpunit.dist.xml: excluded tests/Mcp

All marked with TODO for re-enabling when the package is installed.
