Shared Family calendar and task list; notes default to Family; phone chat and Family card fixes

- Built-in Family calendar everyone with Calendar can edit (data/family)
- Family task list shared by everyone with Tasks
- New notes and lists start shared with the family
- Phone chat sized above the bottom bar and mini player so the message box is visible
- Family page cards no longer overflow on long chat previews
- Tests added and updated
