update

Times were always showing 0 because ISO8601DateFormatter with default
options does not parse fractional seconds, but Prisma/Node.js serialises
dates as "2026-02-20T09:00:00.000Z" (with .000). Every date(from:) call
silently returned nil, so elapsedTime and duration always fell back to 0.

- Date+Extensions: fromISO8601 now tries .withFractionalSeconds first,
  then falls back to whole seconds — single place to maintain
- OngoingTimer.elapsedTime: use Date.fromISO8601() instead of bare formatter
- TimeEntry.duration: use Date.fromISO8601() instead of bare formatters
- TimerView: add TimerUnitLabels view showing h/min/sec column headers
  under the monospaced clock digits
