feat(l2): Gallery app (screenshots as thumbnails, full view with swipe and delete, the saved trails), the clock from NTP while WiFi is up (the router's server from DHCP first), tabs switch on release, Home apps out of Settings

- Gallery: thumbnails 30 to a page, built only while the screen is still (a decode held the loop and a scroll read as a tap)
- segmented(): CLICK_TRIG, so a swipe starting on a screen's tabs doesn't switch them
- Settings > Device > Home apps removed (hold an app on Home instead)
- platformio.ini: a note that the L2 has no microphone on GPIO15 (verified on hardware)
