v2.0.12

Changed

• Added “Editor” filter (Block / Classic) to the Network → Sites list.
• Made “Editor” column sortable with correct pagination support.
• Implemented caching (transients) for site → editor type mapping to improve performance.
• Fixed fatal errors by guarding against count => true queries in sites_pre_query.
• Ensured consistent handling of get_sites() returning arrays vs. counts.
