-- Created by:  AgentNeo
-- Created on:  09/07/2026
-- Description: Insert a new Asset for a project and return the created row.
--              Resolves the shard id via fn_GetProjectShardId (raises if the project
--              does not exist so the API layer can map to 404) and validates the
--              asset type belongs to the same project, raising if it does not.
