Wear app: show sessions

[BoD]

Sorry for the big PR 😅

• Sign in / sign out
• Session list (per day in a pager)
• Current day is automatically selected
• Setting to filter on favorite sessions

am-wear-1.webm

Missing:

• Session details
• Automatically scroll to time of day
• Gray out passed sessions
• Pull (or button) to refresh

Nice to have:

• Automatic refresh when bookmarking on phone
• Bookmarking on watch
