Fix the remaining bare script references in hypr configs

Audited every non-shell context in the repo — hypr, waybar, systemd,
desktop entries — for repo scripts named without a path. Two real hits
beyond the scratchpad bind:

hyprctl_modify_wkspc1 runs from exec-once at every Hyprland startup, so it
has been failing silently on both laptops since ~/.local/bin stopped being
a symlink into the repo. Nothing surfaces an exec-once that cannot find its
binary.

system76's playlistBuilder bind had the same bare hypr_workspace. Its inner
command already used `zsh -lc`, so `play` resolved; the outer call did not.
