feat: alias offline=No bypasses Joomla global offline setting

When an alias domain has offline=No, the plugin overrides Joomla's
configuration.php offline=1 setting. This allows the dev/staging alias
to remain accessible while the main site shows the offline page.

Use case: put clarksvillefurs.com offline for maintenance while
clarksvillefurs.dev.mokoconsulting.tech stays accessible for testing.
