[Feature]: Refactor GET-many endpoints in deployer to allow pagination

[AlphaKeks]

Describe the feature

We should implement pagination for the endpoints that get a list of items from the deployer and gateway. This will be useful for CLI users so they can get only a subset of e.g. projects, rather than all of them. It will also be useful for the console, so we can fetch a subset at a time, rather than fetch them all and then paginate them in the browser.

• Implement pagination for project list (”/projects” endpoint on the router in gateway/api/latest)
• Implement pagination for deployment list
• Consider whether we should follow this up with some filtering, e.g. should we be able to filter project list by project state?

Suggestion or Example of how the feature would be used

Are there more endpoints we should implement this for? Should we consider using cursor pagination for this?
