Subject: [PATCH] fix(webpage): hide Temperatures section when setup has no
 temperature data

renderInstrument() checked setup.temperatures for truthiness, but an
empty JS object is truthy, so LamNI's deliberately-empty temperatures
dict (it has no monitoring device) still rendered an empty
"Temperatures" heading/table. flomni only worked by coincidence since
its _TEMP_MAP always has entries. Adds a hasTemps check
(Object.keys(...).length>0), mirroring the existing hasParams idiom
one line above for the same card.
