fix(desktop): remove forced 1920x1080 modeline, limit LightDM restarts

Browse Source 
On real server hardware (IPMI/BMC AST chip + nomodeset) the VESA
framebuffer is set by BIOS at whatever resolution it chooses (often
1024x768 or 1280x1024). The hardcoded 1920x1080 Modeline caused X to
fail → LightDM crash-loop → SOL console flooded with systemd messages.

- Remove Monitor section / Modeline from xorg.conf — fbdev now uses
  whatever framebuffer resolution the kernel provides
- Add lightdm.service.d/bee-limits.conf: RestartSec=10,
  max 3 restarts per 60s so headless hardware doesn't spam the console
