On Flexpool miners, workers and Etherscan dashboards, min, max and last
computations where based on multiple small time intervals instead of the big

Grafana displays single statistics by grouping 3 values together. If we group
currency and fiat currency (2 values) together, the output is broken. This
commit groups all crypto currency (daily, weekly and monthly) on a single row,
then fiat currencies on a second row.
