dashboard/app: use day long aggregations not week long

Current coverage is a week long data merge for every day.
The goal is to show a monthly data by default and
make daily data available for &period=day requests.
This commit makes the first two steps:
1. Make the day a day long, not a week long aggregation.
2. Enable the month long merges available for &period=month.
