Refactor page routing and point calculation logic

Streamlined the `page` routing structure by optimizing branch and file handling, introducing a reusable `filesInDirectory` method, and cleaning up redundancies. Enhanced `EventGroup` point calculation with incremental updates, new helper methods (`getTeams`, `getTeamsId`), and better handling of unfinished fights.
