Create at the tapped hour after a zoom (#148)

The week/day tap detector captured the hour height when pointerInput was
installed, and pointerInput only restarts when its keys change — so after a
pinch or a Settings hour-height change, taps were mapped against the old
spacing and created events at the wrong hour. Read the height (and the
callback) through rememberUpdatedState instead, and move the offset-to-minute
arithmetic into a tested tappedMinuteOfDay.

+### Fixed
+- Tapping an empty slot in week or day view creates the event at the hour you
+  tapped, after the timeline has been zoomed. Pinching the day taller or shorter
+  — or changing **Hour height** in Settings — left the tap still being measured
+  against the old spacing, so the new event landed at some other hour entirely
