Dominik Csapak 831c43c91b config/tfa: webauthn: disallow registering a token twice
by adding the existing credential id to the 'excludeCredentials' list

this prevents the browser from registering a token twice, which
lets authentication fail on some browser/token combinations
(e.g. onlykey/solokey+chromium)
while is seems this is currently a bug in chromium, in a future spec
update the underlying behaviour should be better defined, making this
an authenticator bug

also explicitly catch registering errors and show appropriate error messages

Dominik Csapak 7f37cacfac config/tfa: set UserVerificationPolicy to Discouraged
the current default is 'Preferred', which is not really useful, as the
(web) client can simply change this to discouraged, since the
webauthn_rs crate does not verify the 'user_verified' bit of the
response in that case

setting this to 'Required' is not really useful either at the moment,
since a user can have a mix of different authenticators that may or
may not support user verification

there is ongoing discussion in the crate how to handle that[0]

we could probably expose this setting(discouraged/required) to the user/admin
and save it to the credential and allow only registering credentials
of the same type or filter them out on login (i.e. if there is an
authenticator that can handle userVerification, require it)

in any case, the current default is not helpful for security, but
makes loggin in harder, since the key will by default want to verify
the user

it's less error-prone (off-by-one!)

Wolfgang Bumiller 9b6bddb24c tfa: remove/empty description for recovery keys
While the user chosen description is not allowed to be
empty, we do leave it empty for recovery keys, as a "dummy
description" makes little sense...

Wolfgang Bumiller a670b99db1 tfa: add webauthn configuration API entry points
Currently there's not yet a node config and the WA config is
somewhat "tightly coupled" to the user entries in that
changing it can lock them all out, so for now I opted for
fewer reorganization and just use a digest of the
canonicalized config here, and keep it all in the tfa.json
file.

Experimentally using the flatten feature on the methods with
an`Updater` struct similar to what the api macro is supposed
to be able to derive on its own in the future.
