Add profile conditions, scene presets, MQTT integration, and Scenes tab

Feature 1 — Profile Conditions: time-of-day, system idle (Win32 GetLastInputInfo), and display state (GUID_CONSOLE_DISPLAY_STATE) condition types for automatic profile activation. Feature 2 — Scene Presets: snapshot/restore system that captures target running states, device brightness, and profile enables. Server-side capture with 5-step activation order. Dedicated Scenes tab with CardSection-based card grid, command palette integration, and dashboard quick-activate section. Feature 3 — MQTT Integration: MQTTService singleton with aiomqtt, MQTTLEDClient device provider for pixel output, MQTT profile condition type with topic/payload matching, and frontend support for MQTT device type and condition editor.
