Improve Playwright Screenshot flakes (#1629)

* feat(playwright): add environment variables to make playwright screenshots less flakey

* feat(playwright): improve test stability by seeding user settings and closing tabs before screenshotting

This commit introduces several changes to improve the stability and reliability of Playwright E2E tests:

- **Seed User Settings**: A new `seedUserSettings` function is added to `playwright-base-test.ts` to pre-configure VS Code user settings. This hides elements like the "Get Started" page, release notes, and recommendations, which can cause flakiness in tests.
- **Close All Tabs Helper**: A `closeAllTabs` helper function is introduced in `webview-helpers.ts` to ensure all open editor tabs are closed before taking screenshots. This prevents visual inconsistencies and flakiness in screenshot comparisons.
- **Removed Flaky Command Palette Test**: The command palette test in `sanity.test.ts` was removed as it was contributing to test flakiness and is not critical for basic sanity checks.

These changes aim to create a more consistent and predictable testing environment, reducing intermittent failures.

* fix(playwright): remove unnecessary VSCode launch arguments

Removes arguments that are either redundant or cause issues in Playwright E2E tests, such as crash reporting, backgrounding, and translate UI features. This helps streamline the test environment.

* test(playwright): Cleanup

Refactor `closeAllTabs` helper to use more descriptive variable names for Playwright locators and clarify the keyboard command used.

* fix(playwright): click mouse after moving to avoid tooltip in settings tests

* fix(playwright): wait for extension activation before screenshot

The `takeScreenshot` fixture now waits for the "Activating Extensions" status message to disappear before taking a screenshot. This prevents flakiness in tests where the screenshot is taken before the VS Code environment is fully ready, leading to incomplete or incorrect screenshots.

* test(playwright): add timeouts to stabilize chat tests

* test(playwright): rename settings test and add index to screenshot name
