quickshell: add initial bar config with per-monitor workspaces

- Vertical bar on DP-2 with rounded-square pills throughout
- Per-monitor workspace groups sorted by screen x position, with
  Nerd Font icons for named workspaces and apex-neon red active indicator
- Bar layout: datetime+weather top, workspaces centered, gamemode+media+notif+system bottom
- Popouts anchor to triggering icon (top-right for datetime/weather, bottom-right for media/notif/system)
- Lock command switched from hyprlock to swaylock
- Hyprland blur/ignore_alpha layerrules for quickshell namespace
