fix(install): fresh installations no longer roll back the first site/customer. GORM's snake_case split HTTPS/MBps into http_s/m_bps, so freshly auto-migrated columns (redirect_http_to_http_s, slice_io_read_m_bps, …) never matched the code — a site/customer create failed the moment auto-SSL ran on a resolving domain. Column names are now flat, with a data-preserving migration that renames legacy columns in place.
fix(wordpress): WP-CLI now runs with the site's PHP version instead of the box default, so WordPress installs and toolkit actions no longer fail when the default CLI PHP differs from the site (e.g. "mysqli extension missing").
fix(email): the "@" separator in the mailbox and forwarder creation forms is no longer clipped.
