Synapse's own media-scanning module (Issue #19) can never see E2EE
attachment content - a structural limit, not a bug. This adds a small
standalone HTTP wrapper around the same ClamAV instance, reachable
from browser JS at /_scan, so the ThreadNet-Web client fork can scan
plaintext both before encrypting/uploading and after downloading/
decrypting - covering both directions regardless of room encryption.
Auth via Synapse's own /whoami endpoint, no separate auth system.
