EW: Make OIDC identity reset consistent with EX

[uhoreg]

Background

Historically EW had many different identity resets, some of which only reset the cross-signing keys and some of which also reset "everything" (meaning any server-side copies of any keys as well as the server side storage as such). The other difference was that in some variants, EW also automatically asked user to set up recovery (on EX this step was separated from the reset flow).

To simplify it for the end users, and make it consistent with EX behavior, only one type of reset will be kept - the one that resets "everything" and does not set up recovery as part of it.

#29227 (which this is split off from) covered reset for legacy accounts. This covers reset for OIDC (MAS) accounts.

Modernizing the screen that is used in case of OIDC (user is directed to MAS web app) is a stretch goal. The minimum is to make sure that the copy of the current modal follows the copy of new designs (current modal on the left, new designs on the right).

The dialog box is MasUnlockCrossSigningAuthEntry from components/views/auth/InteractiveAuthEntryComponents.tsx.

Note that the new design changes the flow. In the existing design, the user clicks on the "Go to your account" button, which opens the account provider in a new browser window. After they are done resetting, they click the "Retry" button. In the new design, it looks like the user clicks the "Continue" button, which will open the account provider in a new browser window, but when it's done resetting, the app is supposed to automagically continue on. @mxandreas is that correct?

I assume there was a good reason why the Retry button was added (e.g. hard to make it work reliably automagically, or perhaps even not possible at all). If that is the case then we can keep the Retry button - I have asked @americanrefugee in Figma to add this button to the designs as well. But I now realized that just adding the Retry button alone may be confusing for the user - we should probably adjust the label of the Retry button as well as the subtitle copy.

I've updated the wording in the Figma file. Lemme know if it's correct now.

Looks good, I have also updated the snapshot in the ticket.
