fix: install meshcentral to fixed path /opt/meshcentral

Node.js 24 on Alpine installs npm global packages to a different
path than /usr/lib/node_modules. Using --prefix /opt/meshcentral
gives a predictable install location.

run.sh updated to use /opt/meshcentral/lib/node_modules/meshcentral.
Bump version to 0.2.4.
