Update a single usage recommendation by its unique identifier.

Supported fields:

• applicable — Set recommendation applicability
• state — Update the recommendation state
• snoozeUntil — Set or clear the snooze timestamp

Omitted values are retained. Set snoozeUntil to null to clear it; changing state alone does not clear an existing snooze timestamp. state and snoozeUntil are separate updates. These edits do not execute cloud-resource changes.
