Overview

Resolves issue #1348 by replacing the hardcoded mock player summary in frontend/app/api/og/game/[id]/route.tsx with dynamic backend data fetching.

Changes Made

1. Dynamic Game Lookup:
   • Fetches game metadata via GET /v1/games/{id} using the configured backend API base URL (NEXT_PUBLIC_API_URL / NEXT_PUBLIC_BACKEND_URL).
   • Supports Edge runtime caching with appropriate revalidation.
2. Player Profiles & Ratings:
   • Dynamically resolves player usernames and Elo/FIDE ratings from game metadata or GET /v1/players/{id} in parallel with graceful fallbacks.
3. Game Outcome & Status Formatting:
   • Accurately computes and formats the outcome display string based on backend status and result states (won, drawn, in progress, waiting, aborted).
4. Resilient 404 Fallback:
   • Returns null whenever a game is not found or fails validation, preserving the default branded card fallback.

Local Quality Assurance & Verification

• Validated route compilation and Edge runtime compatibility.
• Verified dynamic card generation paths with complete, in-progress, and missing game states.
• Confirmed fallback to branded banner when game is not found.

Closes #1348
