Better indicators when a raw secret has changed, and the sealed secret is dirty

[Ian L.]

It can get a little confusing when sealing multiple secrets because there is no clear indicator if the updated raw secret was successfully sealed, and if we even triggered the sealing.

Some ideas:

• Reset the sealed secret output if the raw secret changes
• Disable the seal button after sealing, and only re-enable it if the raw secret changes
• Include an indicator (e.g. icon or message) that the raw secret is "dirty" and needs sealing
• Show a sealed success message or a loading state (maybe something similar to React Suspense, only show it if it takes longer than normal)
