feat(ui): reflect filters/sort/search in the URL

Browse source 
Serialize the active filters to a compact, readable query string (only non-default
values) and parse them back on load, with URL taking precedence over localStorage.
Uses history.replaceState so it never spams browser history. A pasted link now
reproduces the exact view.
