fix(wrapped): eliminate duplicate fetchGitHubContributions call in /api/wrapped route (JhaSourav07#2446)

## Description

Fixes JhaSourav07#2247

The /api/wrapped route was calling fetchGitHubContributions twice for
the same user and year range in a single request. The first call happens
inside getWrappedData(), and the second was made directly in the route
handler to get the calendar for SVG rendering.

With refresh=false this was a harmless redundant cache lookup, but with
refresh=true both calls used bypassCache: true, meaning two separate
GitHub GraphQL requests went out for identical data, burning rate limit
quota twice per request.

Added calendar to the WrappedStats interface and returned it from
getWrappedData() since it was already computed there. The route now
reads calendar directly from wrappedStats instead of fetching it again.
Removed the now-unused fetchGitHubContributions import from route.ts.

## Pillar

- [x] 🛠️ Other (Bug fix, refactoring, docs)

## Visual Preview

No SVG changes — backend logic fix only.
