feat: upgrade MiniMax default model to M2.7

- Add MiniMax-M2.7 and MiniMax-M2.7-highspeed to model list
- Set MiniMax-M2.7 as default model
- Keep all previous models (M2.5, M2.5-highspeed) as alternatives
- Add M2.7 pattern to web UI icon matching
- Add unit tests for model registration and defaults
