We have a method called `fetchDevicesWithVerification` which is currently used in the new Session manager. Let's use it for the (old) Devices Panel too, because it allows us to check the device verification upfront, rather than on the fly, which is going to be handy when that operation becomes async
these are in an async method, but currently use `some`. We need to invent an `asyncSome` (we already have an `asyncEvery`) and use that
... which means making it async
This is ok except we need an "unmounted" guard because it's an old-style componment

Might this be worth doing with Promise.race or similar as one slow or never resolving promise might wedge things up here

Maybe. I'm somewhat keen to keep it symmetrical with asyncEvery, and the semantics are much easier to reason about if the promises happen serially.

That's fair, didn't see asyncEvery

To match L177 in the same file

The problem here is avoiding the implicit cast to boolean if deviceTrust is nullish. We could do something like isVerified = !!(isMe ? deviceTrust?.crossSigningVerified : deviceTrust?.isVerified())) but I'm far from convinced that's clearer.
At L177, we have an explicit check on deviceTrust, so I'd say my variant of this is closer to L177 than yours.

The ! needs to be on .getCrypto()!

matrix-org/matrix-js-sdk#3287 and matrix-org/matrix-js-sdk#3303 added a new API called
getDeviceVerificationStatus. Let's use it.Hopefully this makes sense to review commit-by-commit.
The quality gate isn't quite met but there are cypress tests covering the places where coverage is lacking.
Fixes element-hq/element-web#25092 and element-hq/element-web#25093
This change is marked as an internal change (Task), so will not be included in the changelog.
