fix: Long dashboard titles overflow the navbar tab

[ericlln]

• Moved the title into its own element in the navbar tab so that text-overflow: ellipsis would work properly.
• Tested by creating dashboards with both long and short titles to confirm that long titles are truncated with ellipses, and short titles display in the same way as before.

I'm assigning @dsmmcken for review as this is mainly a styling thing.
