fix(time): accept spaced durations and print whole-second times

tea time create 1 1h25m printed 2026-10-11T18:57:49.588823137Z while time
list printed whole seconds, and "1h 30m" or 2d failed with "duration
must be nonzero whole seconds". Durations may now contain spaces, and
errors name the problem: "invalid duration "2d": use h, m and s units
such as 1h25m". Tracked times are whole seconds everywhere.
