Upstream AmneziaWG 3.x is still shifting under active development
(unanswered kernel-module issues around header protection and
handshake-without-data regressions), so give operators an explicit
opt-out/opt-in instead of always auto-selecting 3.1, and pin the
installed package so unattended-upgrades can't swap the module under
a live server. Surface the running module/tools version and protocol
generation through /health, the CLI status command, and the panel's
server card so a mismatch is visible instead of silent.
