Add free-text day notes with an always-visible notes log

A new 📝 Note quick-action logs a free-text note (with a date, optional
photo, and any text), defaulting to the day you're viewing. Notes are a
distinct "note" event type, so they edit, sync and delete like any other
event, and a new Notes section lists them newest-first across every day —
independent of the day picker — so records like vaccinations stay visible
whatever day you're looking at.
