feat(channels): implement channel connection flows with multi-platform support

- Add comprehensive Channels page with connection statistics and status display
- Implement AddChannelDialog with type-specific connection flows:
  - QR code-based connection for WhatsApp/WeChat
  - Token-based connection for Telegram/Discord/Slack
- Enhance channels store with addChannel, deleteChannel, and requestQrCode actions
- Update electron-store usage to dynamic imports for ESM compatibility
- Add channel connection instructions and documentation links
