Edge Function Build Fixes & Import Resolution

🔧 What's Improved

Auth Email Hook Fix

The auth-email-hook edge function was failing to deploy due to missing npm package mappings. The function imported packages like @lovable.dev/webhooks-js and @react-email/components that Deno couldn't resolve.

Fix: Updated deno.json with proper import mappings and removed the nodeModulesDir setting that conflicted with Deno's native npm resolution.

Database Column Mapping Updates

After PR #14 merged structural changes to the brand_kit_expression table (splitting verbal_style into five numbered columns), three files still referenced the old column name:

• ExpressionValidator.ts
• KnowledgeFilesPage.tsx
• MessagingFrameworkWizard.tsx

All references updated to verbal_style_1 to match the new schema.
