refactor: extract terminal launch logic into shared script

Add terminal-launcher script as a single entry point for launching
foot-based terminals with a given class and command. Migrate all
.desktop files to use it instead of inline foot invocations.

Simplify hyprland keybindings by replacing inline focus_or_launch
with hl.dsp.exec_cmd
