hyprland: port scripts off hyprlang hyprctl syntax

With the Lua config, `hyprctl dispatch` evaluates Lua rather than the
hyprlang dispatcher strings, and `hyprctl keyword` is refused outright
("can't work with non-legacy parsers"). Three scripts still used the old
forms and silently failed.

- toggle_floating (SUPER+W): rewritten around hl.dsp.window.{float,resize,
  center}. The Lua resize dispatcher takes absolute pixels only, so the
  70% is resolved against the logical size of the window's monitor, and
  fullscreen is left first since resize is a no-op while fullscreen.
  Floats every window at 70%x70% now, not just 50%x55% for kitty.
- performance: runtime overrides via `hyprctl eval hl.config{}`; drop the
  removed decoration:drop_shadow for decoration:shadow:enabled; read the
  gamemode flag from `getoption -j` (.bool), which the awk on line 2 had
  been picking the "set:" line out of.
- move_by_rules: movetoworkspace -> hl.dsp.window.move{workspace=N}.
