Add Email Sending Service with Attachment Support (#3455)
# Description of Changes

Please provide a summary of the changes, including:

- **What was changed**  
- Introduced a new `EmailService` for asynchronous email delivery with
attachment support.
- Added `MailConfig` to configure a `JavaMailSender` bean using SMTP
settings from `ApplicationProperties`.
- Created `EmailController` endpoint (`/api/v1/general/send-email`) to
accept multipart/form-data requests for sending emails.
- Defined an `Email` API model to encapsulate recipient, subject, body,
and file input.
- Extended `ApplicationProperties` to include a nested `Mail` class for
SMTP host, port, username/password, and sender address.
- Updated `settings.yml.template` to include SMTP configuration
placeholders.
- Enhanced `.github/labeler-config.yml` to cover all new security- and
API-related source files for automated labeling.

- **Why the change was made**  
- To enable Stirling-PDF to notify users via email—particularly useful
for sending generated PDFs or alerts—directly from the application.
- To centralize mail server configuration in application properties and
streamline onboarding for new environments.
