hyprland: migrate to Lua config (Hyprland 0.55+)

Switch Gaming and Macbook to home-manager unstable which has
configType = "lua" support. Converts the full Hyprland config from
deprecated hyprlang to native Lua:

- flake: add home-manager unstable input for Gaming/Macbook
- hyprland.nix: configType = "lua", settings.config for static sections,
  extraConfig for env/startup/animations/binds/window-rules
- hosts: monitor config updated to hl.monitor({}) table format

Eliminates the windowrulev2 deprecation banner.
