feat(dashboard): interactive sankey highlighting and persistent filters

- Highlight full paths through a clicked node or link in the flow Sankey,
  dimming unrelated nodes/links instead of removing them
- Disable VChart built-in emphasis to avoid crash, use custom highlight sets
- Initialize models filter dialog from currently applied filters so manual
  time ranges are not overridden by preferences; auto-pick granularity by range
- Lift user charts time range/granularity/limit to dashboard as controlled state
