feat: implemented hide on scroll strategy w/ tests

[NikGurev]

Summary

Applied ability of using new scroll strategy in overlay related components.

Existing behavior is unchanged. For popover - it used hide on scroll behavior, so applied new strategy by default

• scroll strategy token in each component still defaults to reposition
• When applied a new strategy, component listens to bounds intersection (hide$) and hides/closes depending on implementation. So strategy simply emits , others react .
• Covered new feature with tests for all related components
• Provided example for popover to visually check realization.
