Restructure Play into dashboard and mission log

[BrainerVirus]

Summary

Turn Play into a proper game-style dashboard so the user sees the companion, featured rewards, and current mission pressure at a glance.

Scope

• Build a main Play dashboard with the banner/pet scene, featured items, and progress highlights.
• Add a mission log tab for all active and completed missions.
• Make the daily mission picker easy to reach from Play.
• Surface quick stats and one small suggestion area to keep the page lively.
• Keep this as a presentation layer over the mission/economy systems, not a new data source.

Acceptance criteria

• Play has a clear dashboard plus a mission log experience.
• The dashboard shows the equipped companion and featured rewards.
• Active missions are visible without opening deep settings.
• The layout stays lightweight and fast.
