The kill-switch previously left comment UI/text visible in several places.
Sweep the whole surface so a comments-off instance shows no trace:
Frontend (main app):
- VirtualFeed grid tile: gate the comment button/count on $commentsEnabled
(was ungated — the only feed surface still showing it).
- admin stats: hide the "Kommentare" count card.
- UploadSheet "Uploads geschlossen" notice, host ban-modal description, and
host/admin unban confirmations: drop the "…und kommentieren" wording.
- export page: drop "Kommentaren" from the keepsake description.
Keepsake export (had no concept of the flag):
- export.rs: thread comments_enabled into the exported data (ViewerEvent),
wired through spawn_export_jobs/recover_exports and their call sites
(host.rs, main.rs).
- export-viewer: gate comment counts (list + grid) and the lightbox comments
section; older exports without the field default to enabled (?? true).
Backend still 403s comment writes when disabled (unchanged) — this is the UI
half so stale clients and archives match.
Verified on the running stack (COMMENTS_ENABLED=false): /event reports
comments_enabled=false, a regenerated keepsake embeds "comments_enabled": false
with no comment UI, and the uploads-closed notice renders "…ansehen und liken."
