fix: forward scroll options for pointer actions

[Mihail Galay (GalayM)]

ScrollMode.None currently scrolls offscreen targets into view because the option is lost before reaching the driver. Forward it through Page's option conversions and the Frame/ElementHandle messages for click, double-click, hover, tap, checkbox actions and drag-and-drop.

Adds browser regression coverage for all four API entry points, document and nested scrolling, visible targets, None/Auto/omitted values, and non-forced click retries.

Validated all 211 regression cases on Chromium, Firefox and WebKit. The full CI browser/platform matrix passes. The related Chromium suites on net10.0 pass 304 tests, with 2 existing upstream skips. dotnet build ./src and dotnet format ./src/ --verify-no-changes -v:diag pass.

A separate prerequisite commit moves ResolveNpmExecutable before instance methods without changing its body. This fixes the existing SA1204 formatting failure on the base branch.

Fixes #3357

🟢 Approval recommended

The changes are narrowly scoped to forwarding an existing option through the last-mile protocol payloads and are backed by targeted regression tests covering the affected action entry points.

Pull request overview

This PR fixes a regression where ScrollMode.None was not preserved for pointer-based actions, causing offscreen targets to be scrolled into view despite the caller explicitly opting out. It forwards the Scroll option through Page-level option conversions and ensures Frame/ElementHandle protocol messages include the scroll field, with new regression tests covering Page/Frame/Locator/ElementHandle entry points and drag-and-drop.

Changes:

• Forward Scroll from Page*Options into the corresponding Frame*Options conversions in Page.cs.
• Include scroll in the protocol payloads sent by Frame and ElementHandle for click/dblclick/hover/tap/check/uncheck/setChecked and drag-and-drop.
• Add a dedicated ScrollOptionsTests regression suite and reorder a tooling helper to satisfy SA1204 member ordering.
