fix(dates): use UTC parsing and display for date-only strings (#351)

Browse Source 
Date-only strings parsed with new Date(dateStr + 'T00:00:00') were
interpreted relative to the local timezone, causing off-by-one day
display for users west of UTC. Fixed across 16 files by parsing as
UTC ('T00:00:00Z') and displaying with timeZone: 'UTC'.
