Replace hardcoded model name abbreviations with dynamic truncation

- Strip common provider prefixes (gemini/, openai/, anthropic/, mistral/, cohere/)
- Truncate names > 24 chars with ellipsis (…) instead of hardcoded abbreviations
- Works generically for any LiteLLM model, not just our Gemini config
