refactor(GetFonts): centralize filterManager/sortStore → fontStore bridge

Move the duplicated $effect blocks that mapped filterManager and sortStore
into fontStore params out of Search, FontSearch and FilterControls into a
single $effect.root in features/GetFonts/model/state/bindings.svelte.ts.

Consumers now bind to the manager/store directly; the bridge is installed
once via a side-effect import from the feature barrel.
