Successfully consolidated all MCP server functionality into unified MCPServer

- Combined external server management from MCPServerManager (stdio/http support)
- Integrated session tracking and heartbeat from EnhancedMCPServer
- Added auto-registration and unified interface from UnifiedMCPServer
- Fixed HTTP server support to prevent crashes on mcp_figma config
- All 15+ agent coordination tools now properly registered and working
- External servers (context7, filesystem, memory, sequentialthinking) starting correctly
- HTTP servers handled gracefully with proper fallback logging
- Application.ex updated to start only consolidated MCPServer
- Ready to remove duplicate files after verification
