feat: Major UX Improvements - Perfect Builder Experience! 🎯

## ✅ 1. Prevent Link/Button Navigation in Builder
**Problem:** Clicking links/buttons redirected users, preventing editing
**Solution:**
- Added click handler in BlockRenderer to prevent navigation
- Added handleClick in TipTap editorProps
- Links and buttons now only editable, not clickable

**Files:**
- `components/EmailBuilder/BlockRenderer.tsx`
- `components/ui/rich-text-editor.tsx`

## ✅ 2. Default Templates Use Raw Buttons
**Problem:** Default content had formatted buttons in cards
**Solution:**
- Changed `[card]<a class="button">...</a>[/card]`
- To `[button link="..." style="solid"]...[/button]`
- Matches current block structure

**File:**
- `includes/Core/Notifications/TemplateProvider.php`

## ✅ 3. Split Order Items into List & Table
**Problem:** Only one order_items variable
**Solution:**
- `{order_items_list}` - Formatted list (ul/li)
- `{order_items_table}` - Formatted table
- Better control over presentation

**File:**
- `includes/Core/Notifications/TemplateProvider.php`

## ✅ 4. Payment URL Variable Added
**Problem:** No way to link to payment page
**Solution:**
- Added `{payment_url}` variable
- Strategy:
  - Manual payment → order details/thankyou page
  - API payment → payment gateway URL
- Reads from order payment_meta

**File:**
- `includes/Core/Notifications/TemplateProvider.php`

## ✅ 5. Variable Categorization (Noted)
**Strategy for future:**
- Order events: order_items_table, payment_url
- Account events: login_url, account_url
- Contextual variables only
- Better UX, less confusion

## ✅ 6. WordPress Media Library Fixed
**Problem:** WP Media not loaded, showing browser prompt
**Solution:**
- Added `wp_enqueue_media()` in Assets.php
- Changed prompt to alert with better message
- Added debugging console logs
- Now loads properly!

**Files:**
- `includes/Admin/Assets.php`
- `lib/wp-media.ts`
