Fix missing user attributes on logs

[cleptric]

We didn't include various user attributes on log messages. If a user was set on the scope, the id, username and email are now being attached.

Pull Request Overview

This PR addresses the missing user attributes on log messages by ensuring that, if a user is set on the event, the log payload now includes the user's id, email, and username. Furthermore, the change refactors the serializer to rely on event properties (such as environment, release, and server name) instead of duplicating these values in the log aggregator.

• Updated test case to validate presence of new user attributes.
• Enhanced the envelope serializer to attach environment, release, server, and user attributes.
• Removed redundant attribute assignments from the LogsAggregator, relying on the event properties.

• Removal of explicit log attributes (release, environment, and server address) is intentional since these are now sourced from event properties in the serializer. Please confirm that omitting these in the aggregator does not remove any necessary context when event properties are not set.

• [nitpick] The user attribute key is set as 'user.name' based on getUsername(), which is acceptable; please ensure this naming convention is consistent with other parts of the codebase and documentation.
