Replaces WordPress wp_mail() with SendGrid's API. Adds a settings page to manage API key, sender info, and test email functionality.

Settings panel with SendGrid API key and sender inputs
This plugin overrides the default WordPress email sending function with SendGrid’s Mail Send API.
Key Features:
This plugin integrates with the SendGrid email delivery service to send outgoing emails via its API instead of the default wp_mail() function.
When enabled, the plugin communicates with the following SendGrid API endpoint: https://api.sendgrid.com/v3/mail/send
Data sent to SendGrid includes:
– Sender name and email
– Recipient email(s)
– Email subject
– Message body (text or HTML)
– Optional headers (Cc, Bcc)
The plugin requires a valid SendGrid API key to function. This credential is stored in your WordPress database and used only to authenticate API requests to SendGrid.
