fix(ui-lvgl): unlock fades away on release, channel names shown as named

Browse Source 
- Unlocking fades the lock screen out while the screen underneath drifts
  into place; the slider unlocks on letting go at the end and springs back
  when let go earlier
- Channel names no longer get a "# " prefix (thread title, channel popup,
  live share targets) -- "#" marks a hashtag channel; favourite contacts in
  the live share list are starred instead
