feat(autocomplete): search loras within active filters of LoRA Manager page

Add /af and /noaf toggle commands (plus /activefilters aliases) to the
loras autocomplete widget. When enabled (default off), suggestions are
matched within the active filters (folder, base model, tags, auto-tags,
license, tag logic) persisted by the LoRA Manager page in localStorage,
keeping the match pool consistent with the list endpoint, including the
global show_only_sfw setting.

Backend: /lm/{prefix}/relative-paths accepts the filter query params and
pre-filters the scanner cache with ModelFilterSet. The presence of the
recursive param signals the filter pipeline to run even without concrete
filters so global settings stay in parity with the list endpoint.
