[Feature] Moderation panel — edit player ELO

[iiamlewis]

Overview

Moderators can edit a player's ELO rating directly from the moderation panel. Used for corrections after exploits, bugs, or confirmed cheating. All ELO edits must be logged with reason.

Scope

• Edit ELO field on any player profile from moderation panel
• Mandatory reason field when editing ELO
• Full audit log: moderator ID, player ID, previous ELO, new ELO, reason, timestamp
• Audit log viewable by admins (not moderators)
• ELO change takes effect immediately

Acceptance criteria

• Moderator can edit ELO from player profile in moderation panel
• Reason field is mandatory — cannot submit without it
• Audit log entry created on every ELO change
• Audit log contains: moderator ID, player ID, old ELO, new ELO, reason, timestamp
• Audit log visible to admins only
• ELO change reflected immediately in game and on leaderboard

Security notes

• Moderators cannot edit their own ELO
• ELO edits should trigger an internal alert if change exceeds a threshold (e.g. ±500)

Dependencies

• Depends on: Moderator role (#ROLE), Player search (#SEARCH)
