Redundancies in legend, update popup

[srsjojo]

• [x] "pavement condition 13" vs "pavement condition 13 one mile"
• [x] "Projects" vs "Planned paving project locations"
• [x] custom configure the popup to say the chart is on a 1-100 scale
• [ ] explain why the chart disappears at the .1 mi zoom level

[srsjojo]

maybe "Condition is on a scale from 0 to 100 (best = 100)"

[rkiniry]

No explanation for chart disappearance at tenth mile segmentation.
