web(d-web4): neutralize inline min-widths + wrap monospace config on <=480px (#442)

The embedded dashboard header info boxes (#miner-info / #network-info)
carry inline min-width (280px / 220px) that the 768px/900px breakpoints
cannot override, and the monospace config lines (stratum URL, the
<ADDR>,<DOGE_ADDR>.WORKER username) are unbreakable tokens. On a phone
(<=414px) these force horizontal overflow that clips the view. Add a
<=480px breakpoint that drops the inline mins to full-width and lets the
long tokens wrap. Static drop-in (served from --dashboard-dir), no rebuild.
