Pull request overview

This PR continues the codebase-wide effort from #269213 by removing a few remaining as any type assertions in tests, replacing them with more precise mock shapes and stronger types.

Changes:

• Update chat request parser tests to stub services without as any by supplying required service-brand and readonly fields.
• Update CDP accessibility domain tests to use AXPropertyName directly, removing an as any cast.
• Update quick input tests to stub ILayoutService without as any by including _serviceBrand.

File	Description
src/vs/workbench/contrib/chat/test/common/requestParser/chatRequestParser.test.ts	Makes service mocks type-correct (e.g., _serviceBrand, events/booleans) so instantiationService.stub(...) no longer needs as any.
src/vs/platform/webContentExtractor/test/electron-main/cdpAccessibilityDomain.test.ts	Uses AXPropertyName for createAXProperty to avoid name as any.
src/vs/platform/quickinput/test/browser/quickinput.test.ts	Removes as any from the ILayoutService stub by providing _serviceBrand.
