fix(auth): drop MiniMaxCN label, show full dashboard after login

- Both OAuth options labelled 'MiniMax', region in parens
- After any login (OAuth or API key), print the same dashboard
  as bare 'mmx' (help panel + quota table) so the user lands on
  a useful view instead of returning to a blank shell prompt
