feat: add MiniMax brand true-color status bar to HTTP requests

- Replace single-icon prefix with bold MINIMAX brand wordmark
- Use 24-bit true color (RGB) matching brand palette:
  - mmBlue (#2B52FF) for MINIMAX wordmark
  - mmPurple (#9333EA) for model name
  - mmCyan (#06B8D4) for region
  - mmPink (#EC4899) for masked API key
- Status bar shows: MINIMAX Region: CN | Key: sk-c...nI7s | Model: MiniMax-M2.7
- Only renders when stderr is a TTY (no effect on redirected logs)
