### What problem does this PR solve?
Issue Number: close #CIR-27838
Related PR: #xxx
Problem Summary:
Querying `information_schema.encryption_keys` exposes the original
Base64-encoded initialization vector and ciphertext through the `IV` and
`CIPHER` columns.
The schema scanner previously copied `iv_base64` and `ciphertext_base64`
directly into the result block. This change masks both fields with `******`
when their values are present, while preserving the existing empty-string
behavior when the fields are absent.
A BE unit test is added to verify both the masked-value and empty-value
cases.
