Remove redundant attachment and embed tests
Eliminated multiple test functions for file attachments and embeds, including TestMsg_AttachFile, TestMsg_AttachFromEmbedFS, and TestMsg_EmbedFile. These tests either duplicated functionality or were no longer relevant to the current code base. Simplifying the test suite enhances maintainability and reduces unnecessary checks.
