cool#9992 lok doc sign: convert the certificate chooser dialog to async

1) Move the try-catch around assing a signature inside the block that
already got the response from the certificate chooser, it's unlikely
that choosing the certificate (and not yet signing) would fail.

2) Convert the dialog to async and allow it to be a jsdialog.

3) Hide not relevant widgets for LOK: we have a single signing
certificate, so the search entry is not useful.

The refresh button has an unclear purpose, as it was initially added
in commit fb9874231fb242b4a6a7d1ce097e66dd4ed8f32e (Caching
Certificates in the CertificateChooser dialog session-wise, 2023-08-26),
but later commit efe414c4a88fde0e2ee1d4016010f21fbd6d01d7 (Don't reuse
CertificateChooser instances, 2024-02-07) disabled this chaching. In any
case, the certificate won't change during the lifetime of a single LOK
view, so hide that as well.

4) Invoke the inner certificate viewer in an async way, too.
