feat: upgrade MiniMax default model to M2.7 (#13593)

## Summary
- Add MiniMax-M2.7 and MiniMax-M2.7-highspeed to both minimax and
minimax-global provider model lists
- Set MiniMax-M2.7 as the new default model (first in list)
- Keep all previous models (M2.5, M2.1, M2) as available alternatives
- Update function calling regex to support M2.7 and all M2.x variants
- Add M2.7 test cases for reasoning and interleaved thinking detection

## Why
MiniMax-M2.7 is the latest flagship model with enhanced reasoning and
coding capabilities.

## Changes
- `src/renderer/src/config/models/default.ts`: Add M2.7 and
M2.7-highspeed entries at the top of both `minimax` and `minimax-global`
model arrays
- `src/renderer/src/config/models/tooluse.ts`: Update function calling
regex from `minimax-m2(?:.1)?` to `minimax-m2(?:\.\d+)?(?:-[\w-]+)?` to
support all M2.x variants including M2.7
- `src/renderer/src/config/models/__tests__/reasoning.test.ts`: Add test
assertions for M2.7 reasoning model detection

## Testing
- Added explicit M2.7 test cases to reasoning and interleaved thinking
model tests
- All existing models preserved as alternatives
