[Feature] Add admin audit log for new user moderation actions #40003
Description
Is your feature request related to a problem?
Currently when admins manually mute, deactivate or flag a new user account, there is no centralised audit trail recording who took the action, when, and why. This makes it difficult to:
- Review past moderation decisions
- Identify patterns in spam behaviour
- Comply with community governance requirements
Describe the solution you'd like
A dedicated audit log under Admin > Moderation that records:
- Timestamp of action
- Admin who performed the action
- Action type (mute / deactivate / flag / dismiss)
- Target user account age at time of action
- Optional reason field
Additional context
This would serve as foundational infrastructure for automated anti-spam systems that need to log their decisions alongside manual admin actions.
