Pre-fill visitor data in Lobbyside widget

[sarupbanskota]

Summary

• Calls Lobbyside.setVisitor() with the current user's email, name, and GitHub username after the widget script loads
• When a user clicks "Join" on the Lobbyside widget, their info is pre-filled in the lobby form so they don't have to type it again
• Also syncs data if the script was already loaded (e.g., navigating back to a page with the widget)

Test plan

• Log in as a staff user, visit a page with the Lobbyside widget
• Click "Join" on the widget card
• Verify the lobby form has email, name, and GitHub handle pre-filled
• Verify fields are still editable
