[PM-18596] feat: Hide SSN Field by Default on Identity Screen

[OneUpWallStreet]

🎟️ Tracking

I'm a heavy user of Bitwarden and I think this could be a pretty useful feature. I haven't linked it to a specific issue or Jira ticket, but I noticed that while credit card numbers are hidden by default, the SSN field in identity items isn't. This change comes from my own experience using the app.

📔 Objective

I feel like the SSN field in identity should be hidden by default because its value is arguably even more sensitive than a password. It doesn't make much sense for it to be in plain text when other sensitive fields, like credit card numbers, are already protected.

I think there's still some work to be done to align it with Bitwarden's design principles. One area for example I'm still not 100% on is adding the proper eventType for the SSN toggle. Any feedback or pointers on that would be awesome.
