Subdominio desconocido ya no redirige a dominio externo. En su lugar,
continua sin tenant y el login pide el tenant manualmente.
Agregados 'nexus', 'pos', 'app', 'dashboard' a subdominios reservados.

- Nginx wildcard config: *.nexusautoparts.com routes to POS app with X-Tenant-Subdomain header
- middleware_tenant.py: resolves subdomain -> tenant_id via nexus_master.tenants.subdomain
- auth_bp: login and employee list endpoints accept tenant from subdomain, URL param, or body
- login.html: auto-detects tenant from subdomain, shows business name, falls back to ?tenant=ID
- tenant_manager: generates subdomain slug from business name on provision_tenant()
- Migration v1.2: adds subdomain column + unique index to tenants table
- setup-nginx.sh: one-command install script for the nginx config
