OpenIcon gallery: all 370 icons on /openicon, with search, filters and terminal glyphs (#199)

Replaces the 47-icon sample with the whole reference set: search by name,
alias or keyword; category chips with counts; UI/brand filter; SVG,
Nerd Font, Unicode or ASCII view (the Nerd Font view uses the official
symbols subset to the set's 349 glyphs, 38 KB woff2, MIT); size and
colour; a detail panel with all three glyphs and codepoints, trademark
notes, copy SVG / <img> / icon("key"), and downloads. Ready for the
optional HQ (full-colour) style: a Simple/HQ toggle appears once icons
carry an hq field. Filters live in the URL.
