Add in-editor Slate setup wizard (Tools > MCP Setup Wizard)

Native UE editor tab (SMCPWizard) so setup happens inside Unreal, not just the
Node CLI. Three sections:
- Remote Control: live status of the :30010 bridge + a button to start it
  (WebControl.StartServer + EnableServerOnStartup).
- API keys: paste/save the agent-gateway Anthropic token (auth.env) and
  ElevenLabs key (integrations.json) — both git-ignored.
- MCP tools: lists the catalogue from tools.json.

Wiring:
- UEBlueprintMCPEditor module registers a nomad tab + a Tools-menu entry.
- Build.cs gains the Projects module (IPluginManager).
- server.js exports TOOLS and only launches the stdio server when run directly
  (isMain), so src/dumpTools.mjs can generate tools.json. `npm run dump-tools`.
