Code Snippets 5.2

Added: Site picker to the Snippets tab. Select a child site to see which saved snippets apply and whether each targets the site directly, through a tag, or through its client.
Added: Code Snippets to the MainWP Dashboard database health check so it can flag missing tables, missing columns, and incorrect column definitions.
Fixed: Database upgrades so older installations get the expected default user ID while preserving saved snippets.
Updated: Strengthened request verification when deleting snippets from child sites.
Updated: Improved Dashboard console security by displaying child-site snippet output as plain text.
