fix(delegation): dynamic model display from settings

- Read ANTHROPIC_MODEL from profile settings instead of hardcoding
- Display model name in full uppercase (GLM-4.7, not Glm-4.7)
- Add null/undefined guard to getModelDisplayName
- Remove hardcoded GLM-4.6/GLM-4.6 (Thinking) display names

Closes #431
