🔄 Token Refresh Logic

**Implemented in:**

  • channels/route.ts
  • message/route.ts
  • history/[channel_id]/route.ts
  • microsoft.ts (centralized refreshAccessToken method)

**Flow:**

  1. Check if token exists and has expires_at
  2. If expired and has refresh_token:
  • Call Microsoft token endpoint
  • Update database with new tokens
  • Continue with original request
  1. If refresh fails, return 401 with TOKEN_REFRESH_FAILED
