Revert proxy complexity: TUN mode handles all routing at OS level

- start_bot_v3.sh: unset ALL_PROXY/all_proxy so TUN VPN handles all traffic
- Revert _direct_session and _tg_session proxy config
- All requests now use standard requests module (goes through TUN)
- Keep Telegram notification functions (tg_signal, tg_scan_summary)
- Keep config.json with bot token and chat ID
