feat(manage): delete photos from /manage, prune leftover pages

/manage/delete/{slug} asks for confirmation, then removes the image,
its sidecar and everything generated from them. Builds now drop day
pages of days without photos and pager pages past the last one, so a
delete or a date change leaves nothing behind.

 In production nginx sits in front: serves `public/` directly, proxies `/upload` and `/manage` to localhost, htpasswd on both. Note `/health` is **not** proxied — nginx only forwards `location /upload` and `location /manage`, so anything outside the box can only reach those two.
 
 ### Managing photos
 
-`manage.go` holds the `/manage` handlers, kept apart from the upload code in `server.go`. They are only registered when the binary runs with `-manage` (NixOS `services.photogallery.manage.enable`, which also adds the nginx location); without it the paths 404 and there is no edit or delete code path at all. The pages are rendered on request from the sidecars (not generated into `public/`), and nothing on the public site links to them. Constraints worth knowing before touching it:

 - An edit only rewrites the `.toml` sidecar. Any key other than `caption` and `date` in a hand-written sidecar is dropped, same as on upload.
 - Slugs from the URL are matched against the photos actually in `content/`, never joined into a path.
