Decommission OnlyBans21

Updated compatibility for Arma Reforger 1.8. Restored the custom decommission action on all vehicles through Vehicle_Base.et. Restored action visibility while holding the repair tool. Preserved the original action-wheel timing and single-rotation behavior. Preserved the requirement that vehicles be unoccupied and the player be within three metres. Preserved randomized physical supply-crate refunds of 50–300 supplies. Fixed the refund crate’s invalid resource path. Added server-authoritative validation, crate spawning, and vehicle deletion. Added one-shot protection to prevent duplicate refunds or repeated deletion. Vehicle deletion is cancelled if the refund crate cannot spawn correctly. Fixed a peer-to-peer stack overflow caused by recursive RPC calls. Removed the unnecessary custom RPC and now use the built-in user-action multiplayer routing. Added a minimal deletion delay to allow action cleanup without starting another UI rotation. Fixed the PostFrame non-replicated action cleanup warning. Passed all project structure, script, prefab, configuration, reference, and naming validation checks.
