System Controls & Hardware Monitor (Integrated Features)

[scardracs]

Description

This PR introduces and integrates a comprehensive set of system monitoring and control tools into the System Control section of rog-control-center.

These features are built on top of the clean feature/battery-stats branch and have been optimized for stability, code quality, and visual consistency.

Included Features

1. Battery Information & Stats

• Battery Info: A new section that contains all the info related to battery and Charge limit.
• Sensor Polling: Background polling for battery capacity health, charge cycles count, and current charging status.
• Power Draw Tracking: Real-time measurement of instant power draw in Watts.
• Autonomy Estimations: Dynamic calculations for estimated time remaining or time to full charge.

2. Hardware Monitor

• CPU Status: Real-time tracking of core temperature (°C), utilization percentage (%), and clock frequency (MHz).
• GPU Status: Dynamic tracking of temperature (°C) and utilization (%), handling offline/disconnected dGPU states gracefully (showing N/A).
• RAM Status: Live memory usage tracking.
• Fan Speeds: Real-time RPM tracking for all system fans (CPU, GPU, and Mid Fan).

3. Agnostic Wayland Display Settings (Refresh Rate)

• Multi-Compositor Compatibility: Dynamic detection of the Wayland compositor backend at runtime (supporting both KDE Plasma's kscreen-doctor and wlroots-based compositors like Sway/Hyprland via wlr-randr). Degrades gracefully if tools are missing. It can't work for GNOME
• wlr-randr Parser: Robust text parser to discover the internal screen identifier (eDP-*) and map available resolutions and refresh rates.
• Auto-Switching: Logic to automatically switch to a power-saving refresh rate when the laptop is disconnected from AC power to maximize battery life.

UI Redesign

• Card-Based Layout: Complete visual redesign of the System page into clean, responsive cards (Battery Information, Display Settings, Hardware Monitor).
• Universal Glyphs: Emojis have been removed from text labels to prevent rendering missing glyph fallback boxes ([]) on Linux configurations lacking complete emoji fonts, ensuring a polished and consistent look.

---

Technical Details & Quality

• Async Polling: Background monitoring tasks are implemented using non-blocking Tokio tasks, ensuring the UI remains highly responsive.
• Testing: Compilation successfully verified and all workspace unit tests pass.
