Lots of unnecessary/repetitive unlocked icons in commit list

Description

Too many unlocked icon in commit list, especially for unsigned commits, simply no need of an "unverified" icon, unless adding vigilant mode as what GitHub does. (example on demo site: https://demo.gitea.com/lunny/TheSession-data/commits/branch/main)

#10425 looks quite smooth and distinguished.
While changes from #31160 simply determines the icon display by whether commit signed (verified) or not. https://github.com/go-gitea/gitea/blob/079a1ffe8f38e0c7570079b21a4d8cec4d90e923/templates/repo/commit_sign_badge.tmpl

I think this proposal is acceptable from this side but that's not a bug.

I think it is a bug, we should avoid showing unnecessary locks.

The fix could be like this: Do not show unnecessary commit sign lock icon #33387
