fix: upgrade tween.js to v25 with explicit group management

[remo-lab]

Summary

In this PR, I upgraded @tweenjs/tween.js from v23 to v25, which fixes #680.

In v25, tween.js removed implicit global group registration. That means tweens are no longer automatically tracked — they must be explicitly added to a Group and updated using group.update(). Without this change, all tween-based animations silently fail.

To address this:

• I created a shared TweenGroup instance inside ThreeManager

• Passed this shared group to AnimationsManager, ControlsManager, and SelectionManager

• Updated all new Tween(obj) calls to explicitly pass the group:

  new Tween(obj, tweenGroup)

• Replaced the global tweenUpdate() call with tweenGroup.update(now) inside the render loop

• Fixed a pre-existing bug where tweenUpdate() was being called twice per frame

What Was Broken (Before This Fix)

All tween-based animations were silently failing, including:

• “Look at Object” camera animation
• Event collision / propagation animation
• Double-click orbit target smooth transition
• Camera fly-through presets

The +/- zoom buttons were unaffected because they directly manipulate the camera and don’t use tweens.

Test Plan

• Load an event at http://localhost:4200/atlas
• Click an object → use “Look at Object” → camera smoothly animates
• Click animate event → collision / propagation animation plays
• Double-click a surface → orbit target transitions smoothly
• Verify +/- zoom buttons still work as expected

---

This upgrade restores all tween-driven animations and aligns the project with the new tween.js v25 architecture.
