feat(recorder): Shift+click to interact with page during Pick Locator

[jameskip]

Summary

• Allow holding Shift during Pick Locator mode to bypass locator selection and interact with the page directly
• When Shift is held, mouse events pass through to the page (clicks, pointer events, mouse moves)
• When Shift is released, Pick Locator resumes normally — no mode toggling required
• Highlight/tooltip clears while Shift is held to give visual feedback

Issue #33280

Test plan

• Added test should shift-click to interact with page while picking locator that verifies:
  • Shift+click triggers the page's click handler
  • Regular click (without Shift) still picks the locator
• Existing pick locator tests continue to pass
