Motivation

On a Soundcore Liberty 5 (A3957), the controls people change all the time were two levels deep: ambient sound mode (noise canceling / transparency / normal), noise canceling level, transportation mode, transparency mode (e.g. vocal mode) and wind noise suppression. You had to open the Sound Modes category, then a dialog for each select or a slider for the noise canceling level. This PR puts them on the first screen after connecting and adds a Quick Settings tile. It also fixes a few auto connect issues, so the app works better in the background.

What changed

Device home screen

feat(android): device home screen with sound mode controls

• The first screen after connecting shows battery levels for each earbud and the case, plus a "Sound mode" card. The card shows the ambient sound mode as large icon buttons, with the mode-specific settings below them.
• The remaining categories are listed under "More Settings". Sound Modes is no longer listed separately.
• Selects with a few short options use segmented buttons or chips instead of a dialog. Small integer ranges (e.g. noise canceling level 1–5) use buttons instead of a slider. The shared controls are in ui/utils/ChoiceControls.kt.
• Settings of the inactive mode are dimmed but still usable. Picking e.g. "Car" while in transparency mode also sends the parent values (noise canceling, transportation), so the choice takes effect immediately instead of only changing a stored value. SoundModeChangesTest covers this.
• The "Migrate Legacy Equalizer Profiles" entry only appears when there are profiles to migrate.

Quick Settings tile

feat(android): quick settings tile for the ambient sound mode

• Shows the current ambient sound mode and its detail (noise canceling level, transportation mode or transparency mode).
• Tapping it cycles through the ambient sound modes. When the device reports its own cycle settings, the tile follows them. Long pressing it opens the app.

Auto connect

fix(android): auto connect after app updates and to already connected devices, feat(android): open the connected device directly and keep auto connect alive

• The auto connect service also starts on MY_PACKAGE_REPLACED, not only on boot, so updating the app no longer disables auto connect until the next reboot.
• When the service starts, it connects to a paired device that is already connected over Bluetooth, since no further ACTION_ACL_CONNECTED will arrive for it. This resolves the TODO in AutoConnectService.
• With auto connect enabled, closing the app no longer stops the device service, so the status notification keeps working in the background.
• Opening the app while exactly one paired device is connected goes straight to that device instead of the device list.

Small fixes

fix(android): translatable notification channel name and earbuds icon for A39xx models

• The notification channel name is now a string resource.
• Models missing from the icon list fall back on their model number. A39xx earbuds such as the Liberty 5 (A3957) now show an earbuds icon rather than headphones.

Translations

Traditional Chinese (zh_Hant) translations are going through Codeberg Translate instead of this PR. The strings added here will be translated there once this is merged.

Testing

• Android JVM unit tests: 13/13 passed
• cargo test -p openscq30-lib --lib --features bundled-dependencies: 228/228 passed
• Android instrumented tests on an Android 17 emulator (en-US locale): 20/20 passed, updated for the new layout. On current master the instrumented tests can't run at all, because the Hilt compiler isn't applied to androidTest. build(android): fix instrumented tests, shrink the native library, update rusqlite to 0.41 #438 fixes that, and these results are with it applied.
• ktlint 1.8.0 (format-check-kotlin): clean
• The Bluetooth and protocol code is unchanged. The new screen and the tile were only tested with demo devices, not with real hardware.

This branch doesn't depend on #438 (no shared files). The two merge cleanly in either order.
