Add a per-server Analytics page scoped to that host, move traffic
settings out of Sentinel, and put metrics settings on Charts.
Surface 4xx/5xx on path rows and restyle deployment logs.
Replace the server-scoped Analytics Livewire component with an
app-wide one that filters by server/application and supports live
refresh. Add a per-bucket status-class time series endpoint/data
class for a stacked-area chart, falling back to the donut when the
Sentinel build doesn't support it. Decorate top-path rows with their
owning domain, expand breakdown dimensions to agent/ip/useragent, and
raise path/breakdown result limits. Capture X-Forwarded-For,
User-Agent, and Referer headers in traefik access logs (now enabled
in dev too) so IP, browser, and referrer breakdowns work. Add
flag-image and referer-host helpers for geo/referrer rendering.
