Subject: [PATCH] Log training sessions onto the selected day, not always today

The Log button stamps the selected day at the current time of day, so a
forgotten session can be back-filled from that day's view. The snackbar
says which day it landed on when it isn't today; Undo/Add note still
work on it.
