Show customer ID and anonymize data in the Customer Activity Log

[ks129]

Questions	Answers
Description?	Added customer ID to the customer data column in the Customer Activity Log (if it is not 0). Implemented anonymization of logs in case of GDPR data deletion. Removed customer ID from erasure request (to avoid connecting customer name with previous account ID and records). The name should be retained in logs for compliance proof and for detecting excess requests.

How to test?	1. Create a new customer account. 2. Request personal data (one or a few times) from the user settings. 3. Check GDPR logs - customer ID should be shown. 4. Delete user data. 5. Recheck GDPR logs - old records shouldn't contain name and the erasure record shouldn't contain customer ID.
