Initial commit: Pireon Admin — headless admin panel and public API

Laravel 13 + Filament 5 admin panel and REST API for a non-profit developer
collective, backed by the Pireon OAuth identity server. The public site is a
separate, server-rendered application consuming /api/public/v1.

+/**
+ * Two records answering at the same URL in the same language.
+ *
+ * `UniqueTranslatedSlug` prevents this on write, but a slug lives inside a
+ * JSON column, so it can never be a database constraint — which means data
+ * that arrived any other way (a seeder, an import, a manual fix) can still
+ * collide. When it does, the public API resolves the URL to whichever row it
+ * happens to reach first.
+ *
+ * Detected in PHP rather than with a GROUP BY on a JSON path, because that
+ * expression is written differently in every database and these tables hold
+ * hundreds of rows, not millions.
