🧰 Admin Controls

Admins (is_admin = 1 on a member) get a separate /admin area:

• Ad review — every new ad, and any edit to an existing one, starts pending and needs approval before it can run (except a suspended ad, which stays suspended through an edit until an admin looks at it again). Approve, reject/suspend, reinstate, delete, adjust weight, or convert to/from a house ad, all from /admin/ads.
• House ads — create platform-owned filler ads (/admin/ads/new) shown when no real advertiser inventory is eligible for a slot, or convert an existing member ad into one.
• Members — view balances, suspend/ban/reactivate accounts, and manually adjust a member's credit balance with a note (/admin/members).
• Sites — view/delete any publisher's slots (/admin/slots).
• Video settings — the target resolution/fps/bitrate every video ad gets transcoded to, so playback never jumps between advertisers' videos; changing it re-transcodes existing video ads in the background.
• Fraud log — every flagged impression/click, filterable by reason.

All uploaded ad creatives (image/audio/video) are validated for MIME type and size, and video is transcoded server-side via ffmpeg, capped at 30 seconds.
