fix(dashboard): move fuzzy suggestions into human formatter

The fuzzy suggestions for no-match filters were in the hint (footer)
while the formatter independently showed 'No dashboards found.' —
producing duplicate messaging. Now the formatter receives titleFilter
and allTitles in the result, and shows the appropriate message:
- With filter, has suggestions: 'No dashboards matching X. Did you mean:'
- With filter, no suggestions: 'No dashboards matching X.'
- Without filter: 'No dashboards found.'
