Are.na Sync dashboard

Adds an Are.na Sync dashboard to your Studio: Shows which Are.na channels are being synced. Displays last sync status and time. Lets editors trigger a manual sync (the plugin calls your backend endpoint). Auto-refreshes when configuration changes. This plugin is part of an ecosystem of packages for syncing Are.na content to Sanity.
