feat: add CWU50 display patch (no-burst) + fix flake syntax

Remove extra '};' that broke flake.nix parsing.
Apply kernel patch '0008-panel-cwu50-no-burst.patch' to remove
MIPI_DSI_MODE_VIDEO_BURST flag in panel-cwu50.c.
Switch nixos-uconsole module to consolidated uconsole-cm5 module.
Keep patches/0008-panel-cwu50-remove-sync-pulse.patch as variant.
