fix(spend): keep quiet heatmap days above the no-data cells (#480)

A measured day was painted with the highlight tint alone, starting at 10% alpha, while padded no-data slots used a 5% text-colour fill. On Breeze Dark the no-data corners therefore rendered lighter than recorded low-activity days, and on Breeze Light whiter quiet days read as emptier than no-data slots. Every slot now shares the no-data base and a measured day overlays its tint, so intensity increases monotonically from no data to the busiest day.
