- ScriptFunction/ScriptExecutionLog 实体（从 CustomFunction 迁移） - ScriptStatus/ScriptExecutionStatus 枚举 - ScriptingDbContext + 两个 Configuration（表名 funcs/func_execution_logs） - EF Core 迁移：RenameTablesForScriptingModule（b_funcs→funcs 保数据） - 新增 LogLines 字段（Logger 输出收集） Task T2 of scripting module refactor
