fix(autocomplete): sync active filters via server-side store (#1091)

The LoRA Manager page kept its active filters in localStorage, which the
ComfyUI-side autocomplete read directly. When the two run in different
browsers, origins, or the ComfyUI Desktop Electron shell, localStorage is
not shared and the active-filters search silently did nothing.

The manager page now mirrors its filter state to a server-side in-memory
store (PUT /api/lm/{prefix}/active-filters), pushed on every change via a
storage-listener hook and once on page load. The autocomplete widget sends
only use_active_filters=true, and the relative-paths endpoint injects the
stored filters into the search, with explicit query params taking
precedence.
