Description

Update email templates and SendGridProxy to dynamically render partner branding (logo, colors, company name) based on partner configuration.

Email templates updated with Jinja2 variables:
- {{partner_logo}} - Partner logo URL
- {{partner_name}} - Partner company name
- {{partner_primary_color}} - Primary brand color
- {{partner_secondary_color}} - Secondary brand color
SendGridProxy.send_email_to_merchant_rep() updated:
- Accepts partner_id parameter
- Loads partner_whitelabel_config from database
- Injects partner branding into template variables
- Uses partner’s from_email if email config authenticated
- Falls back to Twill branding if no config
SendGridProxy.send_status_update_email() updated similarly
All email sending functions pass partner_id
Template rendering tested with partner branding
Emails display correctly in email clients (Gmail, Outlook)
Fallback to Twill branding works when partner config missing
