feat: implement link click analytics with daily aggregation and dashboard display

[divyanshim27]

Closes #562

Summary

Implements end-to-end click tracking for platform links. Every redirect increments a LinkClick record; users see per-link click counts on their dashboard.

Changes

• prisma/schema.prisma — new LinkClick model with cascade delete
• prisma/migrations/... — generated migration file
• app/[username]/[platform]/page.tsx — fire-and-forget click record on redirect
• app/api/analytics/route.ts — authenticated endpoint returning grouped click counts
• Dashboard UI — click count badge next to each link

Design Notes

The click record is non-blocking (fire-and-forget with .catch(() => {})) so it never slows down the redirect. The analytics endpoint uses Prisma groupBy for efficient aggregation without fetching raw rows.

Warning

Review limit reached

@divyanshim27, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 35 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Thanks for working on this feature @divyanshim27 ! The current preview build is failing due to a TypeScript error:

Type error: Cannot find name 'link'.

prisma.linkClick.create({ data: { linkId: link.id } }).catch(() => {});

It looks like link is being referenced before it's defined. Please move the analytics insertion to a point where the link object has already been resolved (for example, just before the redirect), then push an update. Once the build passes, I'll continue reviewing the implementation.
