Subject: [PATCH] feat(TournamentStats): update internal tournament scoring
 logic and UI enhancements

- Revised scoring system for internal tournaments to assign points based on placement (1st = 100, 2nd = 99, etc.), with adjustments for tied ranks and a cap at 101 points.
- Refactored `groupPointsFromRankings` function for improved clarity and efficiency.
- Enhanced the InternalTournamentStats component UI, integrating a dialog for better user interaction and accessibility.
- Updated localization strings across multiple languages to reflect the new scoring system and UI changes, improving user understanding and experience.
