📝 Walkthrough

Walkthrough

This PR adds Next.js page metadata exports to multiple pages across Blade, Club, and Guild applications. Most pages receive static metadata with title and description fields. One dynamic form page uses an async generateMetadata function to fetch form data. The PR also corrects a typo in the judge results page metadata and augments OpenGraph metadata across sponsor and layout files with image entries.

Changes

Cohort / File(s)	Summary
Blade Admin & Application Pages (Static Metadata) apps/blade/src/app/admin/banquet-raffle/page.tsx, apps/blade/src/app/admin/forms/[slug]/page.tsx, apps/blade/src/app/admin/hackathon/control-room/page.tsx, apps/blade/src/app/admin/roles/configure/page.tsx, apps/blade/src/app/admin/roles/manage/page.tsx, apps/blade/src/app/hacker/application/[hackathon-id]/page.tsx, apps/blade/src/app/judge/dashboard/page.tsx, apps/blade/src/app/member/application/page.tsx	Added static metadata exports with page titles and descriptions for SEO purposes. Each adds Metadata type import and exports a constant with title and description properties.
Blade Form Page (Dynamic Metadata) apps/blade/src/app/forms/[formName]/page.tsx	Added async generateMetadata() function that fetches form details via API and dynamically sets the page title. Returns "Blade | Form Not Found" on API failure for graceful fallback.
Blade Judge Results (Typo Fix) apps/blade/src/app/judge/results/page.tsx	Corrected metadata title from "Blade | Hackthon Results" to "Blade | Hackathon Results".
OpenGraph Enhancements apps/blade/src/app/sponsor/page.tsx, apps/club/src/app/layout.tsx, apps/guild/src/app/layout.tsx	Enhanced OpenGraph metadata with images array and properties (title, description, url, siteName) across sponsor and layout files for better social media sharing.

We don't really need nor want SEO or metadata on admin/judge pages. Best to leave that out.

Im curious how it looks in embeds when it's just ${form.title}. I feel like we might want to do Blade | ${form.title} for consistency. If you could include pictures of embeds of either type (or another I missed), I'd appreciate that a lot. There are sites online that'll let you preview metadata -- I think they're good enough for this purpose.

Overall solid; The Open Graph is big 🔥 I'm dying laughing at that typo you fixed
