Same root cause as the station-observation fix (this uses the same
open-data portal, same UTC DATETIME field): the raw UTC string was
passed straight through to the frontend as a display label, which
JS's Date parser then reads as local time for a string with no
timezone suffix — silently showing observation times 2-3h behind
the newsroom's actual clock. Internal recency filtering (isRecent)
was already self-consistent either way; this only affects display.
Classify all 65 LVĢMC stations reporting water temperature (56 inland
WTEMD + 9 coastal SEDUT) into the six Ūdens zones by geography, and
report the real min/max across each zone's currently-reporting
stations instead of one hand-picked station's single value shown
twice. Drops readings older than 12h so a stuck sensor can't skew a
zone's range.
