fix: use destroy_server for sprite delete to support org users (#1538)

The sprite case in buildDeleteScript called `sprite destroy` directly,
bypassing ensure_sprite_authenticated and destroy_server. This meant
SPRITE_ORG was never detected, so org users got "sprite not found"
errors and orphaned sprites continued incurring charges.

Align with every other cloud (hetzner, digitalocean, fly, gcp, aws,
daytona) by calling ensure_sprite_authenticated then destroy_server,
which applies _sprite_org_flags automatically.
