chore(collections): surface FDA Drug Reference in Medicine > Standard

HOLD UNTIL 1.34.0 GA. Merging early breaks v1.33.0 installs.

The manifest is fetched live from main
(collection_manifest_service.ts: refs/heads/main/collections/kiwix-categories.json),
so every install on every version picks this up the moment it merges — not on
their next upgrade.

`type: "dataset"` does not exist anywhere in v1.33.0: zero hits across
admin/app, admin/inertia and admin/types. It is new in 1.34.0. On a v1.33.0 box
this entry would render as an installable resource with no code that
understands its type and a URL that is not a ZIM, so the install path breaks
for users who are not running the version that introduced the feature.

Held back until GA for that reason, which also means 1.34.0 would otherwise
ship a working Drug Reference that cannot be discovered from Content Explorer.
Entry is byte-identical to the one already on rc.
