merge: maestro/tsk_tFMU7-hKzfOf [tsk_tFMU7-hKzfOf] codes 激活码模块

解决与 1A 骨架的冲突：module 统一为 github.com/wangjia/pangolin/server
（codes 分支原用 pangolin/server，7 个源文件 import 已改写）；
go.mod require 并集(redis 取 9.20.1)；Makefile 以骨架为基底并入
build-codegen/test-unit/test-integration target。
go build/vet 通过，codes 单测通过。
