hub: unified customer page, blocked status, dashboard merge

- Replace separate config detail and report detail pages with unified
  /customers/{id} page showing both config info and live report data
- Add "blocked" status for customers (hidden from dashboard, notifications
  suppressed, still accepts reports)
- Dashboard now shows config-only customers as "PENDING" status
- Customers list: all rows link to /customers/{id}, show BLOCKED badge
- New actions: block/unblock, push config to controller, auto-create
  config from report data
- /configs/{id} now redirects to /customers/{id}
- Add config-badge CSS classes for MANAGED/MANUAL/BLOCKED badges
