feat(redis): add proxy/flush/isolation/resize/modify commands and resource-type dispatch

New commands:
- modify-name, modify-password
- flush, isolation, resize
- list-block, list-proxy
- create-proxy, delete-proxy, resize-proxy

Refactor:
- Introduce `describeRedisMode` to dispatch `delete`/`restart` by resource
  type instead of guessing from the id prefix (`uredis` / `uhredis` /
  `uregionredis` / `udredis`)
- Add `BlockRow` / `ProxyRow` row types

Deps / testdata:
- Bump `github.com/ucloud/ucloud-sdk-go` to `v0.22.90`
- Update `cmdtree` / `completion` golden testdata for redis
