feat: add optional custom label field for links, overriding auto-detected platform name

[divyanshim27]

Closes #563

Summary

Adds an optional customLabel field to the Link model. When set, it overrides the auto-detected platform display name. Fully backward compatible — all existing links without a label continue to show the platform name.

Changes

• prisma/schema.prisma — customLabel String? on Link model
• prisma/migrations/... — generated migration
• app/api/links/route.ts — POST accepts and persists customLabel
• app/api/links/[id]/route.ts — PATCH allows updating customLabel
• Dashboard UI — optional label input in link form
• Public profile — renders customLabel ?? platform

Why

Users with personal blogs, Notion pages, or niche platforms (Hashnode, Polywork) had no way to give their link a meaningful name. This unblocks those use cases with zero breaking changes.

Warning

Review limit reached

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

Next review available in: 17 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 the contribution @divyanshim27 ! The preview deployment is currently failing, but the attached build log is truncated before the actual error message, so I can't determine the root cause yet.

Could you check the full Vercel build log (or run npm run build locally), identify the first error, fix it, and push an updated commit? Once the preview build passes, I'll continue reviewing the implementation.
