fix: openai response should contains model (#841)

* fix: openai response should contains `model`

- Update model attributes in `claudeHandler` for `relay-claude.go`
- Implement model type for fullTextResponse in `relay-gemini.go`
- Add new `Model` field to `OpenAITextResponse` struct in `relay.go`

* chore: set model name response for models
