Tournaments data outdated and inefficient pagination

[gogaz]

Issue Report:

1. Did you encounter this recently, or has this bug always been there? I started working with tournaments yestarday. Pagination didn't seem to work but tournaments data looked up to date
2. Encountered behaviour: /tournaments/joinable, /tournaments/open and /tournaments/1k both return the exact same data which is outdated regardless of the page argument.

Below createTime indicates 20 September 08:21:34 UTC and updatedAt refers to 08:22:58 UTC
