feat(models): 增加模型显示名重命名 (#614)

* feat(models): add WUI model display aliases

Persist display-only model aliases in Web UI app config, surface them in the model selector/search, and keep canonical model IDs for Hermes calls.

* fix(models): improve WUI model alias editing

* fix(models): clarify unlisted model picker

* fix(models): scope aliases to providers
