- IQDB responses carry no preview/file data, so candidates only showed an
ID; the SPA now enriches them with one batched posts lookup (preview,
rating, score, favourites, dimensions, tag preview)
- Candidate tiles are selectable instead of instantly resolving: picking
one shows its info and an explicit 'Link selected post' button
- Linking a post now fetches the e621 original into the library and
drops the staged upload; when the staged file's MD5 already equals the
post's file, the staged copy is moved instead (identical bytes)
- Keep the file URL in stored e621 metadata; sanitize the new candidate
fields server-side
