- Watchdog tab: live system health (RAM bar + thresholds, load, uptime, daemon), docker watchdog strikes + skip list + restart history, stability strikes + reboot log, resource pressure alert card, config inventory (mem limits, required, pause/stop lists)
- Swapped partnership/arrs tab order; FallBack between partnership and watchdog
- Plugin source tree moved from Plugin/usr/local/emhttp/plugins/varaverk/ to Plugin/unraid/
