Server-authoritative interaction via UCF3InteractionAuthorityComponent.

Client intent is sent to server, validated, then reflected through replicated target state.

Validation covers authority, target validity, interaction interface, range, and optional line of sight.

Includes replicated door, pickup, persistent button, momentary button, optional demo input, and prompt UI examples.

Persistent demo actors are late-join safe.
