feat(claw402): add DeepSeek V4 models and default to Flash (#1491)

* feat(payment): add new DeepSeek V4 models to claw402 endpoints and pricing

- Introduced "deepseek-v4-flash" and "deepseek-v4-pro" endpoints in claw402ModelEndpoints.
- Updated modelPrices to include pricing for the new DeepSeek V4 models.
- Added model constants for the new DeepSeek V4 models in the trader component.

* refactor(claw402): update default model to deepseek-v4-flash across components

- Changed the default model for Claw402 from "glm-5" to "deepseek-v4-flash" in multiple files, including the AI model handler and onboarding logic.
- Updated model constants and configurations in the trader component to reflect the new default model.
- Enhanced the model configuration modal to accommodate the new default model setting.
