[ECO Bounty] ioTexScan Address Converter lacks validation for invalid input

Summary: The Address Convert tool on iotexscan.io allows users to enter arbitrary, non-address text (e.g., "Htekakak...") without displaying an error message or validation prompt.

Steps to Reproduce:

1. Navigate to the Address Convert tool on iotexscan.io.

2. Enter an invalid string of text (like "Htekakaksksksskkfnfjfn") into the input field.

3. Observe the output.

Expected Result: The system should validate the input and show an error message such as "Invalid Address" or "Please enter a valid io or 0x address."

Actual Result: The tool accepts the invalid text and displays it as the "converted" result, which could confuse users.
