Subject: [PATCH] test(services): add error path test for
 MemoryContext::read_content

This commit adds a unit test to verify that `MemoryContext::read_content`
correctly returns a `ServiceError::Execution` error when attempting to
read a source that does not exist in the context.

The test ensures that the error variant is correct and that the error
message contains the expected diagnostic information.
