Console Fixes: Safari Rows, Dialogs, Notices and the Tour

What's changed

• In Safari, clicking a row in a console list (for example Databases) opened the last row of that list instead of the one you clicked; each row now opens itself, and middle-click, Cmd-click and Copy Link work anywhere on the row
• Closing a dialog and asking for it again within a fraction of a second (for example Cancel, then straight to Confirm it's you) no longer shuts it again moments later
• With your device set to reduce motion, dialogs now only fade in and out instead of also sliding and scaling
• Dismissed system notices and the dashboard's testimonial request card no longer appear for a moment when the page reloads before disappearing
• Restart product tour (in the Help menu and the account menu) and Take the tour again (on your Profile page) now take you to the dashboard and start at the welcome step; before, the tour opened on whatever page you were on, so the Dashboard and Create steps had nothing to point at
• The product tour now follows your sidebar: it skips services that are not available to your project, adds steps for Logs, Uptime checks and the Activity log, keeps keyboard focus inside the tour, finishes even if you click a resource link on the last step, and shows a message with Close for now if saving your progress fails
• On the changelog page, Subscribe to updates now opens the newsletter sign-up
