fix: correct error message for clan tag length (BUG-07) (#3946)

## Description:

The code was checking `clanTag.length > MAX_CLAN_TAG_LENGTH` but
returning `"tag_too_short"`. This fix corrects the error message to
something more appropriate or ensures the logic matches the message.

**Fix:** Corrected the error message key from `"tag_too_short"` to
`"tag_too_long"` when the length exceeds the maximum.

## Please complete the following:
