Mask text in paste textarea

[db39]

A user on the forum often enters secrets in TinyPilot's paste textarea. They have suggested an option to mask the text similar to how a password input field would, to prevent anyone seeing the plain text on screen.

Thumbs up!

+1 from me. I would keep this as the default too, so if a user selects to mask the field it remains masked for future uses until they unmask it.

This is done now (see the linked PRs above):

The UI also remembers the last toggle position.
