Six server-rendered pages (overview plus volume server, filer, S3, master and worker detail) built from shared chartCard and statCard components, following the existing Bootstrap card and table conventions. Charts are inline SVG, so no chart library is pulled in. Pages show a 'no metrics yet' notice until the first scrapes land.
