# Admin Complaint Notification Email Fix

## Problem
When a new complaint was created, the admin notification email was being sent as plain text without using the branded HTML email template system.

## Root Cause
The `notify_admins_new_complaint()` function in `apps/complaints/tasks.py` was generating plain text emails with bilingual content (English/Arabic) but not rendering any HTML template.

**Location:** `apps/complaints/tasks.py` lines 2408-2500

## Solution

### 1. Created New Email Template
**File:** `templates/emails/new_complaint_admin_notification.html`

**Features:**
- ✅ Extends `emails/base_email_template.html` for consistent branding
- ✅ Hospital logo header with gradient background
- ✅ Priority/severity badges with color coding:
  - 🔴 Critical
  - 🟠 High
  - 🟡 Medium
  - 🟢 Low
- ✅ Complaint details grid (reference, title, priority, severity, status)
- ✅ Patient information section (name, MRN, phone, email)
- ✅ Hospital/department section
- ✅ Description preview
- ✅ Action required notice
- ✅ View complaint CTA button
- ✅ Professional footer with hospital branding

### 2. Updated Task Function
**File:** `apps/complaints/tasks.py`

**Changes:**
1. Added import: `from django.template.loader import render_to_string`
2. Updated `notify_admins_new_complaint()` function (line 2436)
3. Now renders HTML template with complaint context
4. Sends both HTML and plain text versions

**Code Changes:**
```python
# Before: Plain text only
message_en = f"""Dear {admin.get_full_name() or 'Admin'},
A new complaint has been submitted..."""

NotificationService.send_email(
    email=admin.email,
    subject=subject_en,
    message=message_en,  # Plain text only
    ...
)

# After: HTML + Plain text
context = {
    'admin_name': admin.get_full_name() or 'Admin',
    'priority_badge': priority_badge,
    'is_high_priority': is_high_priority,
    'reference_number': complaint.reference_number,
    'complaint_title': complaint.title,
    'priority': complaint.priority,
    'severity': complaint.severity,
    # ... more context variables
}

html_message = render_to_string(
    'emails/new_complaint_admin_notification.html',
    context
)

NotificationService.send_email(
    email=admin.email,
    subject=subject_en,
    message=message_text,  # Plain text fallback
    html_message=html_message,  # HTML template ⭐ NEW
    ...
)
```
