ksmithandClaude Sonnet 5 092f1de585 Fix stale custom emoji image after delete-and-reupload (#18)
The image-serve endpoint's Cache-Control: max-age=300 let a browser
keep serving an already-cached image for up to 5 minutes after a
delete-and-reupload swapped in a different file under the same
shortcode URL. Switched to no-cache, which forces revalidation on
every use -- still cheap, since FileResponse's own ETag/Last-Modified
make an unchanged file a 304, not a full re-transfer.
