Automatic database env vars, a redesigned topology view, and whole-project backups

Managed Postgres and Redis addons now inject their connection details straight into your deployed containers: DATABASE_URL, PGHOST, PGPORT, PGDATABASE, PGUSER and PGPASSWORD for Postgres, REDIS_URL, REDIS_HOST, REDIS_PORT and REDIS_PASSWORD for Redis. No more wiring these by hand.
Postgres now has an explicit link and unlink control on each project, matching the one that already existed for Redis.
The Secrets tab shows a new read-only "Managed by Pierrr" section listing every key injected this way, so it's always clear where they come from.
The project topology view has been redesigned into a tiered layout: proxy, frontend, backend, cache and database, instead of a flat row of boxes. Docker networks no longer show up as their own nodes, shared networks now collapse into a single edge between the containers that use them, with a count label when several links overlap and a hover highlight across the whole network. Click an edge to see the individual links in a modal. The same redesign applies to the internal admin server topology view.

Apps stuck in a fast crash-restart loop were incorrectly shown as running (green). Status is now derived from Docker's restart count and correctly reported as failed.

Backups now cover a whole project (its Docker volumes plus any linked managed database) as one named run, instead of one backup per container. Backup history shows the run's name rather than a list of containers.
The project detail page and the admin server page no longer wait on the topology graph to load. The rest of the page renders immediately while the graph streams in behind a skeleton loader.
