Olivier 25cf0167c1 Enhance 14900k configuration with streaming display support and virtual EDID generation
- Added a new `streaming-display.nix` module to configure a headless 4K virtual output for Sunshine and Moonlight.
- Introduced a Python script `generate-virtual-edid.py` to create a virtual display EDID with 4K capabilities.
- Updated `configuration.nix` to integrate the new streaming display module and enable related services.
- Modified `displays.nix` to accommodate the new streaming display settings and ensure compatibility with existing GPU passthrough configurations.

# Monitor layout for 14900k.
# NVIDIA (default): DP-3 ultrawide, HDMI-A-3 + DP-4 side/top stack; DP-2 virtual 4K when streamingDisplay enabled.
# Intel iGPU (gpu passthru): DP-1 ultrawide, HDMI-A-2 Samsung to the left.
# Niri: `extraSettings` (KDL via `extraConfig`, other wrapper-modules keys) + `extraBinds` (merged keybinds).
# Hyprland: `chiasson.desktop.hyprland.settings` (merged in HM when `chiasson.desktop.hyprland.enable`).
#TODO[epic=Moderate] Clean this up, move to host's configuration.nix.
