feat(ui-core,ui-lvgl): sound in the Core, L2 speaker via ES8311, Sound settings, melody editor

Browse Source 
- genericBuzzer I2S path (BUZZER_I2S): an audio task synthesises the notes
  with eased edges and keeps the DMA queue fed with silence between sounds;
  ES8311 setup; amp powered through the board only around sounds
- ui-core/SoundControl.h (mode, volume, built-in sounds, melody model),
  SoundNotifier moved to the Core, chanctl::melody, schema Sound page
- L2: notifications, alarm / timer ring, locator sounds, Settings > Sound,
  melody editor with the playing note lit, per-chat sound, mute icon
- noteIndex() on every buzzer backend; scrolling popups past screen height
