Restructure UX and seed a fully simulated organisation

Rework the dashboard, environment topology view, header navigation, and
status rendering, and standardise selects on a shadcn-vue component.

Replace the thin database seeder with a SimulatedEnvironmentSeeder that
builds a fully wired, mostly-running organisation (ACTIVE server fleet,
managed + GHCR registries, Gitea source provider, ClipBin app with
production/staging environments, services, slices, endpoints, managed
variables, build artifacts, and a completed/in-progress/failed operations
history) so the new UI renders against realistic data.
