feat: add MiniMax-M2.7 and MiniMax-M2.7-highspeed model support

- Add MiniMax-M2.7 and MiniMax-M2.7-highspeed to KNOWN_ALIASES in
  model-name-normalizer for mixed-case resolution
- Add both models to minimax subscription knownModels config
- Add minimax-m2.7 and minimax-m2.7-highspeed to curated model list
  in PurgeNonCuratedModels migration
- Update MiniMax provider subtitle to reference M2.7 as the latest
- Update tests to cover new M2.7 alias resolution
