• [x] Tap to wake (swipes ignored)
• [x] Double tap to wake (2 taps in <= 1 second)
• [x] Settings entry to choose wake mode
• [x] Whatever settings is used for wake mode, night mode overrides it with "Button"
• [ ] Battery usage test? Looks fine without interaction (-7% in 12 hours), will test next week with real-world usage
