fix(explore): show a requested album as queued, not absent

`library-status-indicator` has had three states since it was written
and produced two: all eight call sites were a two-way ternary between
`in-library` and `not-in-library`, so the `queued` state it styles and
labels was unreachable.

The result was the app contradicting itself on one page. An album added
to the request list showed a plus and announced "is not in your
library", forty pixels from a filled button reading "Wanted".

The rule was written at eight places, which is why none of them had all
of it, so it is `utils/library-status.ts` now: owning outranks wanting,
a satisfied request is not queued, and a request is by MBID — a track
inside a requested album is not itself requested and still says so.

`explore-view` gains the `downloadStore` subscription both detail views
already had, registered `whileActive` because it is a cached view that
never unmounts. `top-results-row` needs its own: its host re-rendering
sets the same `results` array back, so Lit stops at the property and
the row never hears about a change.

*
* Two rules decide the answer, and both are about honesty rather than
* precedence for its own sake:
*
* - **Owning outranks wanting.** A request that has been satisfied by
* any route — downloaded here, ripped, bought elsewhere — is not
* news; what the user has is.
* - **A request is by MBID, and the badge answers about the entity it
* is on.** A track inside a requested album is not itself requested,
* so it stays a plus. Saying otherwise would promise that clicking
* it later would find *that* recording.
*
* A `satisfied` request is deliberately not `queued`: nothing is coming.
* A `paused` one is, because the user did ask for it and it is still on
* the list — "queued" is a slight overstatement of a paused request and
* a much smaller one than "not in your library".
