The most recent hour of data is sometimes wildly inaccurate

[jparyani]

Specifically in the % of blocks proposed by the Flashbots mev-boost relay by hour graph: The most recent hour is sometimes wildly off (I just saw it say that flashbots landed 80% of blocks), since it's a partial hour. Suggestions: the most recent hour should sum to less than 100% to signify partial data, or we shouldn't include the most recent hour at all

Might also be a problem in Hourly average block reward of Flashbots mev-boost relay blocks, although to a lesser extent.

Fixed this to remove last hour (if hourly chart) and last day (if daily chart) in internal test dashboard and production dashboard.
