Improve Ingame UI ✨ (#3212)

## Description:

- **Dynamic sidebar offset for top bars** - GameLeftSidebar,
GameRightSidebar, and PlayerInfoOverlay now shift down when SpawnTimer
and/or ImmunityTimer bars are visible (7px per bar). Implemented via
events.
- **Fixed text overflow** in HeadsUpMessage.ts (Random spawn message is
long)
- **Fixed inconsistent text sizing** in EventsDisplay 
- **Alliance icon horizontal** in PlayerInfoOverlay so the size of the
overlay doesn't change if there is an alliance
- **Nation relation coloring** - Nation player names are now colored
based on their relation
- **Background & Blur Unification**
- **Border Radius & Page Edge Gap Standardization**
- **EventsDisplay collapsed button:** Fixed badge hidden / inline-block
CSS conflict (conditional rendering), added gap-2 between text and badge
- **Right panel spacing:** Changed right container from sm:w-1/2 to
sm:flex-1 to fill remaining space
- **Leaderboard**: Rounded grid corners (rounded-lg overflow-hidden),
removed last-row border, added `willUpdate` for auto-refresh on
hide/show click, plus button styled to match toggle buttons
- Other little CSS fixes (margins etc)
