Migrate to pagy

[Tlazypanda]

Please describe the desired behavior.
Currently we are using will_paginate gem for pagination but pagy offers better performance and saves memory.
Follow up to #8326

Hey @jywarren @cesswairimu using this issue as master issue will be adding pagy for different routes in smaller prs 😅 Also document/catch any important bugs here as well 😅

[cesswairimu]

cool, haven't used pagy before will check it out. Thanks

[jywarren]

Thank you! Yes, pagy seems to be massively faster... and lower memory usage. I hope this will be really helpful!

Also, this could be implemented through a lot of ftos or hacktoberfest issues. I think managing this like #6579 would be good too to keep track of remaining changes.

[Tlazypanda]

Yes, I also think we should create some issues out of this 😅 for hacktoberfest maybe we can maintain the list of functions in which this has been implemented in the issue description
