Security: Serve /media single-range only
http.ServeContent honours any number of comma-separated ranges and
chunkReader caches one 512 KiB slice, so a Range header alternating
between two chunks costs a substring() query per range: one 1 MB header
could make Postgres read tens of gigabytes for a single anonymous
request. Browsers and download managers only ever send one range, so a
multi-range header is dropped and the file served whole.
