* perf(server): check shared link asset access without scanning the album
checkSharedLinkAccess runs on every thumbnail, preview, playback and asset
info request made through a shared link. It joined every asset of the
link's album and only then filtered on an array overlap across four
outer-joined columns, so each request cost O(album size).
Split it into two branches (link assets, album assets) that find the
requested ids through the asset pkey / livePhotoVideoId index and then
probe the album_asset pkey.
Median per request, PG 14, 1.36M-asset instance:
| album behind the link | before | after |
|-----------------------|--------|---------|
| 290 assets | 2.1 ms | 0.17 ms |
| 150k assets | 296 ms | 0.19 ms |
* chore: clean up
