Frontend feature: add first-time user checklist card on GameLobby

[CMI-James]

Background

New users would benefit from a lightweight onboarding checklist that highlights the key setup and first-run tasks inside the main app surface.

Feature Focus

First-time user checklist

Where to Implement (Exact Targets)

• frontend/src/pages/GameLobby.tsx
• frontend/src/services/global-state-store.ts
• frontend/tests/components/GameLobby.test.tsx

What to Implement

• Add a dismissible checklist card for first-time users.
• Track completion or dismissal state locally.
• Keep the checklist content concise and actionable.

Interface / Endpoint / Method Details

• The checklist should disappear or collapse once it is no longer useful.
• State should persist predictably across reloads.
• The implementation should not block returning users from reaching core actions quickly.

Acceptance Criteria

• Implementation is complete in the specified files/modules.
• Behavior is reachable through the intended route, component, or contract method.
• Existing unaffected behavior remains stable.
• Code quality checks pass for the touched subsystem.

Required Tests

• Add tests for first-run checklist rendering, dismissal persistence, and behavior for returning users.

Definition of Done

• PR includes implementation, tests, and any necessary docs updates.
• Reviewer can verify behavior directly from code and tests without assumptions.
