add `proxy_protocol` option toggle

[vortigont]

Hi!
Pls, consider adding a feature to toggle proxy_protocol option as described in CONFIG_PARAMS

Thanks!

Added in the latest update!

Toggle via TUI:
Settings > [8] Toggle PROXY protocol

Or update directly and restart:

mtproxymax update
mtproxymax restart

After enabling, the engine will parse HAProxy PROXY protocol headers on incoming connections, preserving the real client IP when running behind a reverse proxy.

Default: false (disabled). Header parse timeout: 500ms.
