[COMPANY SERVER] Allow to authenticate with Authorization BEARER

[chibenwa]

Why

CF #3435

Hi, Our JMAP endpoint does not support basic auth, it only supports Bearer token authorization, either via OAuth (with pre-registered client id) or by manually creating an API token. We do not support OpenID Connect. Therefore it looks like there's no way to currently connect Twake-Mail to your Fastmail account, sorry. The issue of OAuth requiring pre-registration is well known in the email community, and we are working with other major vendors on a new autodiscovery mechanism and OAuth profile that will hopefully resolve this in the future. Kind regards, Neil.

THus, in order to support FASTMAIL users we shall add a way to pass application tokens....

How

On the tmail login page when OIDC auto discovery failed add a Advanced settings foldable section.

If unfolded it displays a field Applicative token and a little explanation Some JMAP services do not support login via password for third party apps but instead allow generate applicative tokens. and a Login button.
