feat(admin): comprehensive functionality pass across admin apps (Codex review)

- Restore admin order creation (top blocker):
  - New createAdminOrder server action wrapping create_order_with_items RPC with proper getAdminUser + can_manage_orders + brand scoping.
  - AdminOrdersPanel now supports ?new=true with working modal form (customer, stop/ship, dynamic items with fulfillment/price/qty, live total).
  - Fixed dashboard "New Order" and "Create your first order" links; added /admin/orders/new redirect.
  - Success flow: toast + redirect to list.

- Product edit reliability and admin flows hardened.

- Form a11y + validation foundation (cross-cutting):
  - AdminInput now generates stable ids, sets htmlFor, forwards required/aria-required/aria-describedby to children.
  - All admin forms benefit (labels programmatic, required semantics real).

- Integrations: non-secret fields (email, name, phone for Resend/Twilio) no longer masked as password by default. Only isSecret fields use type=password + toggle.

- Advanced/AI settings pages now expose real content (cards + links to actual config) instead of pure redirects.

- Permission hardening example: water-log admin creates now enforce getAdminUser + can_manage_water_log + service key.

- Systematic coverage of admin "apps": orders, products, stops, communications, wholesale, water-log, time-tracking, route-trace, settings (billing/integrations/ai/apps/etc), import, users, reports, etc. via exploration + targeted fixes. Empty states, toasts, scoping, quick actions improved.

- Updated MEMORY.md with full pass summary, test instructions, and remaining items from Codex review.

Non-destructive focus during pass; used dev auth for verification. Core blockers from review now addressed for testing.

See session plan.md for detailed execution guide.
