fix: omp.json -- compact time segment (drop day prefix + clock icon, just HH:MM)

Operator: "time/date is too large for the size containts -- powerlines
should be compacted a small amount".

Time segment was rendering as ' icon 8,15:50 ' (~12 cells). Now just
' 15:50 ' (~7 cells). Saves ~5 cells of right-block reach which gives
more room for the path / git / executiontime segments to breathe.

Operator can extend the format back to include date / day / icon via
mios.html if they want a busier prompt.
