feat: give yolo a distinct amber cursor

yolo's desktop is only ever seen through a Moonlight window, so its cursor
needs to be tellable apart from the client's at a glance. Bibata-Modern-Amber
differs in both colour and silhouette from Nordzy.

Threads the theme through an option rather than setting it in one place: it
was hardcoded in cursor.nix, in hl.env, in the setcursor autostart, and twice
more in darkman's mode scripts, which re-set it on every light/dark switch and
would have reverted the override.

Also drops a stale hl.env pointing HYPRCURSOR_THEME at rose-pine-hyprcursor,
which no host installs.
