Surfaces the metrics the agent now collects (task #868). Adds a viewer-facing fleet page (/plugins/host_agent/) with per-host cards (CPU/mem/disk/load/temp, stale flag) and a per-host detail page (/plugins/host_agent/<id>/) — the link the fleet widget already pointed at but had no route for. Detail page shows current gauges (CPU, memory incl. swap/cache, load, network rx/tx, disk I/O, temp max, memory/cpu/io PSI), per-core CPU bars, per-mount filesystem bars, and per-interface/disk/sensor breakdowns, plus history charts (utilization %, throughput B/s, load & pressure) over a selectable range. Charts use a linear epoch-ms x-axis so no Chart.js date adapter is needed. Stale state uses the plugin's stale_after_seconds threshold. Repoints the host_resources widget detail link from admin settings to the new fleet page. Completes milestone #68 (task #867). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Central widget registry. Each entry describes one widget type that can be
|
|
# placed on a dashboard. Plugin widgets declare which plugin must be enabled.
|
|
#
|
|
# "params" is a list of configurable parameters for the widget. Each param:
|
|
# key - form field name (stored in config_json)
|
|
# label - human-readable label
|
|
# type - "select" (only type currently supported)
|
|
# default - default value (int or str determines how it's parsed from the form)
|
|
# options - list of {value, label} dicts
