[explorer] task: Added convert message to utf8 feature

[AnthonyLaw]

What was the issue?

• The explorer transaction message field didn't support the hex string (drop first 0 bytes in message) for UTF-8.

What's the fix?

• Added a button, so the user can switch from the default view to UTF8
• It only supports the non-encrypted message and the payload in hex string.

Can you fix linting?

Can you fix the apexcharts conflict? You will need to delete the package-lock.json to repo. Thanks.
