feat(site_domain): restore convenience fields to Site_Domain_Base

Add account_name, account_code, account_enable, account_enable_from/to,
site_enable_from/to, site_domain_access_key, logo_path, style_href,
script_src, and google_tracking_id to Site_Domain_Base.

These fields were present in Site_Domain_FQDN_ID_Base but were lost
during the v1/v2 -> v3 migration. The v_site_domain view already
provides them via JOINs, so no DB changes are required.
