Introduced the `EmailAttachmentContext` class to represent email
attachments, with properties for file name, content, content type,
inline display behavior, and content ID. Used conditional compilation
to support both .NET Framework and .NET versions.
Updated the `EmailContext` class to include an `Attachments`
property, enabling emails to include attachments as byte arrays or
file paths.
Enhanced the `LimilabsEmailService` class to handle attachments:
- Added the `AddAttachments` method to process inline and regular
attachments.
- Integrated attachment handling into the email-building process.
Replaced the `Email` record with the new `EmailContext` record to introduce additional context and functionality in email handling. Updated property definitions to distinguish between .NET Framework (`set`) and other frameworks (`init`).
Modified `SendingEmailEvent` to use `EmailContext` for the `Mail` property. Updated mappings in `EmailMappingProfile` to map `SendEmailCommand` to `EmailContext`. Adjusted `SendEmailCommandHandler` to use `EmailContext` when mapping requests.
Refactored `EmailSender` to use `EmailContext` in its `Send` method, including updates to method signatures and documentation. Updated all related test classes (`EmailSenderTests`, `EmailSenderUrlOverloadTests`, `SendingEmailPublisherTests`) to validate the behavior of `EmailContext`, ensuring consistency and thorough testing of the transition.
These changes ensure compatibility across frameworks and improve the maintainability of the email handling process.
