Self / ally arts cast on the hero when pointed at an enemy

Arts with launch type 2 (buffs, auras, heals) are only valid on allies
or without a target; with an enemy under the cursor the game dropped
the order. Orders of a player hero for such arts lose a non-ally target,
which casts them on the hero. The launch type comes from the art
definition tables (game/engine/arts.h, tools/arttable.mjs).

Also: skill keys check the relocated taskbar slots (all 7), Ghidra
data labels (g_ names in names.txt).
