Update Seed Phrase Functionality on Account Import

[rickycodes]

I had the thought the other day that the seed phrase input should be treated as a password; any user using something like pass doesn't really need to have the seed phrase visible in the UI (and likely doesn't want it to be?).

Rational:

I keep my seedphrase in a password manager that has a "copy to clipboard" functionality. the idea being that I never want to display my seedphrase (or passwords) on screen (in plain text). the textarea is now a password field and you can toggle back to a textarea if you need to:

By default the seed phrase input is treated as a password field waiting to accept precious data from the user clipboard:

Now I can import my seedphrase without ever displaying it on screen:

If I need to input the seed phrase manually i can choose to show the seed phrase textarea:

Notes:

This obviously needs some design love, some text to be translated etc. but I just wanted to open this to kick off a conversation.

This should be good now that we've had input from the design team

As a password manager user who uses it with MetaMask, this would make me comfortable swapping vaults while sharing screen, and that’s neat!
