fix(slider): add async to spring animation

[gauthier-th]

Description

Due to the update of react-spring to v10 in #2874, the buttons of the slider in the Discover page where not working anymore.
This PRs fixes this and also adds a small margin to enable/disable the buttons when the scroll is very near the beginning/end of the scrollWidth.

  • Enhanced scroll position threshold detection with refined boundary offset calculations.

📝 Walkthrough

Walkthrough

The Slider component's scroll position boundary logic now includes a margin offset that adjusts when state transitions between "end" and "middle/start" occur. The animation system was refactored to convert the slide function to async, removing the global useSpring onChange callback and instead awaiting animation completion with per-call onChange behavior.

Changes

Cohort / File(s)	Summary
Slider Animation Refactor src/components/Slider/index.tsx	Added margin offset to scroll boundary transitions, converted slide to async function with awaited setX.start(), replaced global useSpring onChange with per-call spring config onChange behavior.

Poem

🐰 A slider hops with graceful spring,
Now waits for animation's swing,
With margins drawn and boundaries tight,
Each scroll transition feels just right,
The async dance makes rhythm bright! 🎪

104-142: ⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Reuse handleScroll() after the animation.

These branches still recompute isStart/isEnd with the old exact thresholds, so the new 5px margin is ignored immediately after a button-triggered slide. If newX lands inside that buffer, the arrow state can be wrong until the debounced onScroll catches up.

Suggested simplification

       await setX.start({
         from: { x: scrollPosition },
         to: { x: newX },
         onChange: (results) => {
           if (containerRef.current) {
             containerRef.current.scrollLeft = results.value.x;
           }
         },
         reset: true,
         config: { friction: 60, tension: 500, velocity: 20 },
       })[0];

-      if (newX === 0) {
-        setScrollPos({ isStart: true, isEnd: false });
-      } else {
-        setScrollPos({ isStart: false, isEnd: false });
-      }
+      handleScroll();
     } else if (direction === Direction.RIGHT) {
       const newX = Math.min(
         scrollPosition - scrollOffset + visibleItems * cardWidth,
         containerRef.current?.scrollWidth ?? 0 - clientWidth
       );
       await setX.start({
         from: { x: scrollPosition },
         to: { x: newX },
         onChange: (results) => {
           if (containerRef.current) {
             containerRef.current.scrollLeft = results.value.x;
           }
         },
         reset: true,
         config: { friction: 60, tension: 500, velocity: 20 },
       })[0];

-      if (newX >= (containerRef.current?.scrollWidth ?? 0) - clientWidth) {
-        setScrollPos({ isStart: false, isEnd: true });
-      } else {
-        setScrollPos({ isStart: false, isEnd: false });
-      }
+      handleScroll();
     }

instead of the current setScrollPos(...) conditional blocks so arrow state is
computed consistently (use the existing containerRef, newX and handleScroll
