feat(gateway): unified proxy support for Discord and Telegram with macOS auto-detection

- Add resolve_proxy_url() to base.py — shared by all platform adapters
- Check HTTPS_PROXY / HTTP_PROXY / ALL_PROXY env vars first
- Fall back to macOS system proxy via scutil --proxy (zero-config)
- Pass proxy= to discord.py commands.Bot() for gateway connectivity
- Refactor telegram_network.py to use shared resolver
- Update test fixtures to accept proxy kwarg
