feat(civitai): record search filters in history entries

History entries stored only the query or tag term, so restoring a
search dropped every filter, and filter-only browsing was never
recorded at all.

- SearchHistory.add takes an optional params dict stored on the entry
- get_search records non-default filters: type, sort, period, base
  models, nsfw, username, favorites
- filter-only searches are recorded as 'filter' entries labeled with
  the filter values
