Add global recent-deployments feed for the projects dashboard

The RECENT DEPLOYMENTS section queried the builds table, so
image-sourced services — which deploy without building — never
appeared and the dashboard reported "no deployments yet" while
containers were running.

- GET /api/v1/deployments lists latest deployments across the
  caller's services, joined with service + project names, ordered
  newest-first with a bounded limit
- ProjectsPage consumes it via listRecentDeployments; the DEPLOYS
  stat card now counts real deployments
- is_admin is now projected in register/upsert user responses, and
  the Better Auth mirror grants admin to the first mirrored account
  (previously only the legacy register path did)
