fix: stabilize frontend tests and drop webkit from CI

- Drop webkit from CI workflow and Playwright config (Chrome + Firefox
  are the supported browsers)
- Set retries: 2 in CI to handle intermittent failures from timing
  sensitive operations (list attribute clearing, server restarts)
- Fix clearAuthorship helper to use force:true to bypass toolbar-overlay
  div that intermittently intercepts clicks after text selection
- Fix admin restartEtherpad helper: increase poll intervals, add
  explicit timeout, use toHaveValue with timeout instead of toBeEmpty
- Convert clear_authorship_color tests to use Playwright auto-retry
  assertions (toHaveAttribute) instead of one-shot getAttribute calls
