feat: v1.1.8 — user-server assignment, VM/LXC ownership, smart login redirect, RBAC migrations

- Migration 20: user_servers association table (User ↔ ProxmoxServer)
- API: GET/PUT /api/users/{id}/servers — assign servers to users with workspace-conflict validation
- API: GET /api/users/{id}/server-assignments — enriched server list (assigned + compatible flags)
- Non-admin server filter: intersection of assigned_servers and workspace servers
- Migration 21: dashboard:view = false for user role (new key format)
- Migration 22: proxmox.cluster.manage → cluster:manage for admin role
- API: GET/PUT /api/{server_id}/vm/{vmid}/owner — VM/LXC owner assignment (admin-only)
- Login: smart redirect based on user permissions after authentication
- Login: returnUrl param support for post-login redirect
- Roles API: user_count field per role in GET /api/roles
- node_uptime added to server detail API response
- Remove redundant PermissionChecker from GET /users HTML route
