perf(luci): eliminate excessive router CPU load during LuCI session

Browse Source 
- Optimize get_ui_state backend by reading /proc natively instead of spawning pidof
- Avoid spawning readlink and redundant ubus queries in state.uc
- Cache positive tachyon_runtime_network_configured checks for 5s
- Back off idle UI state polling interval from 3s to 10s (60s when tab is hidden)
- Back off TachyonLogWatcher interval to 30s
- Pause Dashboard and Monitoring polling when browser tab is inactive (Page Visibility API)
- Fix cleanTabId to ensure inactive tab pollers and timers unmount properly
