feat: Add media_name support for WhatsApp templates document files (#12462)
## Description

This implementation adds support for the `media_name` parameter for
WhatsApp document templates, resolving the issue where documents appear
as "untitled" when sent via templates.

**Problem solved:** Documents sent via WhatsApp templates always
appeared as "untitled" because Chatwoot didn't process the `filename`
field required by the WhatsApp API.

**Solution:** Added support for the `media_name` parameter that maps to
the WhatsApp API's `filename` field.

## Type of change

- [x] New feature (non-breaking change which adds functionality)
- [x] This change requires a documentation update

## How Has This Been Tested?

Created and executed **7 comprehensive test scenarios**:

1.  Document without `media_name` (backward compatibility)
2.  Document with valid `media_name`
3.  Document with blank `media_name`
4.  Document with null `media_name`
5.  Image with `media_name` (ignored as expected)
6.  Video with `media_name` (ignored as expected)
7.  Blank URL (returns nil appropriately)

**All tests passed** and confirmed **100% backward compatibility**.

## Technical Implementation

**Backend Changes:**
- `PopulateTemplateParametersService`: Added `media_name` parameter
support
- `TemplateProcessorService`: Pass `media_name` to parameter builder
- `WhatsappCloudService`: Updated documentation with `media_name`
example

**Frontend Changes:**
- `WhatsAppTemplateParser.vue`: Added UI field for document filename
input
- `templateHelper.js`: Include `media_name` for document templates
- `whatsappTemplates.json`: Added translation key for document name
placeholder

**Key Features:**
- 🔄 **100% Backward Compatible** - Existing templates continue working
- 📝 **Document Filename Support** - Users can specify custom filenames
- 🎯 **Document-Only Feature** - Only affects document media types
-  **Comprehensive Testing** - All edge cases covered

## Expected Behavior

**Before:**
```ruby
# All documents appear as "untitled"
{
  type: 'document',
  document: { link: 'https://example.com/document.pdf' }
}
```

**After:**
```ruby
# With media_name - displays custom filename
{
  type: 'document',
  document: {
    link: 'https://example.com/document.pdf',
    filename: 'Invoice_2025.pdf'
  }
}

# Without media_name - works as before
{
  type: 'document',
  document: { link: 'https://example.com/document.pdf' }
}
```
