helpers:

• API helper: routers/api/v1/utils
• modules/util

"move modules/util/paginate.go to modules/paginate/paginate.go"

We are still adding new code to the util package. So I guess it's so far so good?

ps: IMO instead of keeping issues open, I think it's better to write some PRs to refactor ... if it's worth and it is necessary 😁

I feel utils is too vague for a package name, and it's unclear what's actually inside.

We should either use gitutil, webhookutil... or put those into respective modules or services

We close issues that need feedback from the author if there were no new comments for a month. 🍵
