Hide Full License Key IDs on Subscriptions Page for Enhanced Privacy

[Blaec-CoCalc]

Is your feature request related to a problem? Please describe.
Yes, displaying full License IDs by default poses privacy concerns and increases the risk of unauthorized access to license keys.

Describe the solution you'd like
On the Account -> Subscriptions Page, show only the last few digits of the License IDs in the description column. Implement a feature that requires an explicit action (e.g., clicking a button) to reveal the full License ID. William already created the expanded view, so just removing the License ID (or at least partially) would suffice.

Suggestion: Hide full license IDs on the page below unless one is specifically expanded (which is already implemented).

Additional context
This change would align with privacy best practices and enhance user security. It would ensure that sensitive information is not readily exposed, thus protecting users from potential misuse. It would be useful for demoing purposes (at least to me personally).
