Fix proxy auto-restarting after intentional stop (#49)

When stopping via mtproxymax stop or TUI, the container would restart
because Docker's --restart=unless-stopped policy and the Telegram bot's
auto-recovery both tried to bring it back.

Fix:
- Set Docker restart policy to 'no' before stopping
- Create /tmp/.mtproxymax_stopped flag on intentional stop
- Bot health check and auto_recover() skip recovery if flag exists
- Flag is cleared on next mtproxymax start/restart
