refactor(models): rename model display names for clarity and consistency

- Updated display names for multiple Anthropic and OpenRouter models to shorter, clearer versions.
- Removed deprecated Anthropic models: claude_3_7_sonnet, claude_opus_4, claude_opus_4_1, claude_sonnet_3_7.

Test plan:
- Verified that model display names are updated correctly in the codebase.
- Ensured no references to deleted models remain.
- Ran existing tests to confirm no regressions.
