feat: display friendly model names and add fuzzy label matching

- Add missing model entries (Opus 4.6, dated Sonnet/Haiku variants,
  DeepSeek v3/r1 aliases, Mistral/Codestral short names, Qwen hyphenated IDs)
- Add date-suffix stripping and prefix fallback to getModelLabel so
  canonical pricing IDs resolve to clean names (e.g. Claude Sonnet 4.5)
