Fix Dire Beast (120679): summoned beasts now attack the hunter target

The spell script spell_hun_dire_beast summoned the zone "Beast" guardian but
never ordered it to attack, and the ~108 summon templates had no AIName/ScriptName,
so the beasts idled next to the owner instead of engaging the target.

Add a dedicated ScriptedAI npc_pet_hun_dire_beast (mirroring npc_pet_hunter_snake_trap,
minus the snake-specific level-40 health formula and poison) that, on spawn, attacks
the summoner target (owner GetVictim / getAttackerForHelper), and bind it to the 108
inert level-1 friendly "Beast" summon templates via sql/sylvania/dire_beast_ai_20260705.sql.
