fix: avoid React 19 element.ref warning on web

[dohooo]

Fixes #857
Also addresses #903

Description

• remove the GestureDetector child ref from ScrollViewGesture
• derive the non-loop overscroll limit from shared containerSize state instead of measure(containerRef)
• add a dedicated React 19/web regression that simulates the upstream element.ref read and asserts the exact warning count stays at 0

Review

• I self-reviewed this PR

Testing

• I added/updated tests

Commands run in this branch:
