Consider removing the timeout after successful decryption to improve UX

We need to investigate if there are any benefits to waiting 1000 ms before showing the decrypted page. For example, it might help with loading the iframe in the background, improving the perceived performance since it might have loaded in the background instead of being shown as a white page to users.

If we don't get any benetfits from the delay, removing it would improve UX.

By removing the success status message, we could also delete some parts of the decrypt template:

• success helper
• some tailwind classes won't be used anymore
• The unlocked icon won't be used anymore and can be removed
• If we don't swap between icons, the code toggling .hidden for icons could be removed too.

All in all, this would save about 4 kb from the decrypt template.
