• I've tried running main-labeled docker image and the issue still persists there
• I'm running a supported version of the application which is listed here

Describe the bug (actual behavior)

In the header we use string, but add the first symbol '0' in the begining.
Earlier we used the version 1.1 and it's correctly recognise string type in the header and just omit the first symbol.
Now we have upgraded to version 1.3 because this contains important improvement for us, but found out that our case recognises as HEX probably based only on the first symbol.

Expected behavior

Show header as a string

Your installation details

1.3 version of Kafbat. Confluent Kafka 7.9

Steps to reproduce

write some string in the header and add 0 in first position.

Hi, @maldini8626
Here is the logic of Header type detecting:
https://github.com/kafbat/kafka-ui/blob/main/api/src/main/java/io/kafbat/ui/util/ContentUtils.java
I assume that you have some kind of special symbols in your strings, which cause make it switch to binary mode.
If you could share test with your data or data we could check what is the root cause.
