feat(luci): KISS rewrite for System Hub and SecuBox Dashboard
- System Hub overview.js: self-contained with inline CSS, 6 status cards
(hostname, uptime, services, CPU, temp, health score), 3 resource bars,
quick actions, services table, 5s polling, dark mode
- SecuBox dashboard.js: removed external deps (api, theme, nav, header),
inline CSS, header chips, stats cards, health panel, public IPs,
modules table, quick actions, alerts timeline, 15s polling, dark mode
