v1.0.6-beta.021 - fix: resolve stale system update detection on admin page
- Lowered the Next.js fetch cache revalidation for the GitHub releases API from 1 hour (3600s) to 30 minutes (1800s) in /api/admin/update-check/route.ts.
- Added export const dynamic = 'force-dynamic' to prevent the route from being statically generated with stale data.
- This fixes the discrepancy where the Admin page's System Health card would fail to show newly released versions that other endpoints (like the Homepage widget) had already detected.
