Merge pull request #1514 from johndoe6345789/claude/fix-playwright-locators-5ZoHs

Fix Playwright strict mode violations in template E2E tests

- template-card/list-item prefix selectors: use toHaveCount(8) instead of
  toBeVisible since the prefix selector matches all 8 template elements
- text=Overview: use role-based locator (tab) to disambiguate from heading
- text=Workspace: use label-based locator to disambiguate from nav link
