fix(energy-complex): suppress EIA price cards when live tape covers same commodity (koala73#2009)

EIA wtiPrice/brentPrice are weekly survey data (can be a week stale)
while the live tape shows real-time Yahoo Finance futures for CL=F and
BZ=F. Showing both together produced two different prices for WTI and
Brent with no context, confusing users.

When the live tape has live data for CL=F or BZ=F, hide the
corresponding EIA price card. EIA production and inventory metrics
(the unique value of that data source) are always shown.
