dwindown c599bce71a fix: Add markdown parsing, variable replacement, and logo fallback ...

🐛 Email Rendering Issues Fixed:

1. Markdown Not Parsed
   ❌ Raw markdown showing: ## Great news...
   ✅ Created MarkdownParser.php (PHP port from TypeScript)
   ✅ Parses headings, bold, italic, lists, links
   ✅ Supports card blocks and button syntax
   ✅ Proper newline handling

2. Variables Not Replaced
   ❌ {support_email} showing literally
   ✅ Added support_email variable
   ✅ Added current_year variable
   ✅ Added estimated_delivery variable (3-5 business days)

3. Broken Logo Image
   ❌ Broken image placeholder
   ✅ Fallback to site icon if no logo set
   ✅ Fallback to text header if no icon
   ✅ Proper URL handling

4. Newline Issues
   ❌ Variables on same line
   ✅ Markdown parser handles newlines correctly
   ✅ Proper paragraph wrapping

📦 New File:
- includes/Core/Notifications/MarkdownParser.php
  - parse() - Convert markdown to HTML
  - parse_basics() - Parse standard markdown
  - nl2br_email() - Convert newlines for email

🔧 Updated Files:
- EmailRenderer.php
  - Use MarkdownParser in render_card()
  - Add support_email, current_year variables
  - Add estimated_delivery calculation
  - Logo fallback to site icon
  - Text header fallback if no logo

🎯 Result:
- ✅ Markdown properly rendered
- ✅ All variables replaced
- ✅ Logo displays (or text fallback)
- ✅ Proper line breaks
- ✅ Professional email appearance

📝 Example:
Before: ## Great news, {customer_name}!
After: <h2>Great news, Dwindi Ramadhana!</h2>

Before: {support_email}
After: admin@example.com

Before: Broken image
After: Site icon or store name
