refactor(core): paging classes inheritance

Description

refactor(core): paging classes inheritance

• introduced polymorphism in hopes if making future refactoring of paging logic easier
• added parent class PageQuery to *PageQuery classes
• added OrderColumn interface to *OrderColumn enums

How to test

Probably not needed since tests pass, but deploy on devel and play around with paginated tables just to be sure

Other information

In the end this is just a slightly modified version of !4325. I decided not to move OrderColumn fields into PageQuery, since in order to deserialize this kind of polymorphism (OrderColumn interface field in an abstract parent class - that cannot be instantiated) via Jackson would require a custom deserializer and/or more complex annotation magic and the benefit of having the field extracted into PageQuery would not outweigh the introduced complexity.
