feat: natural language queries respect UI filters (v1.2.0)

- AskRequest now accepts optional filter fields: services, actor, operation,
  result, start, end, include_tags, exclude_tags
- ask_question merges NL-extracted constraints with explicit UI filters
- Frontend sends active filter state with every ask request
- Show filter hint below ask input when filters are active
- Add tests for service+result filtering and actor filtering in /api/ask

Bump version to 1.2.0
