fix(eq): stop the phone speaker from impersonating a Bluetooth device

deviceToMap handed the builtin_speaker id to EVERY output type its `when`
did not name. A car stereo on LE Audio (TYPE_BLE_HEADSET) or an automotive
bus (TYPE_BUS) therefore arrived in Dart under the phone speaker's own id,
carrying a type that maps to `desconocido` -- which slipped past the
type-only esBase guard and persisted a device entry keyed builtin_speaker.
From that moment on, every playback through the phone's own speaker matched
that entry, so the green active-output dot stayed pinned to whatever the user
had renamed it to (a car, in the reported case) whether or not anything was
connected. The dot was never wrong; the row was poisoned.

Give unnamed output types their own `other:<type>:<address>` id namespace,
and match esBase by id as well as by type so no future native regression can
re-create the collision. A guarded one-time migration purges what the
collision already persisted from all three device-keyed maps.

Fix the ranking too: builtin_speaker sat inside the priority list as a peer,
so any type absent from that list sorted BELOW the always-present speaker
and could never win. The speaker is now the explicit last resort, externally
connected outputs outrank it, and virtual or call-only sinks (earpiece,
telephony, remote submix, SCO) are ranked below it so they can never be
reported as where music is playing.

Route every AudioDeviceInfo.getAddress read through a version-guarded
helper. It is API 28 with minSdk 24, and two pre-existing unguarded calls in
this same method were latent NoSuchMethodError crashes on Android 7-8.1.
Android lint for :app goes from 8 errors to 6.

Also lets the user manage the list, which is how they recover from a bad
entry without waiting for a release: a remove action clears a device's
preset, name and matrix entries, unnamed rows show their transport and
address tail instead of a raw bt_a2dp:AA:BB:... id, and the green dot
finally carries a tooltip and a semantics label saying what it means.

Device QA pending for wired and USB outputs: no jack or adapter available to
exercise those paths. Their detection is unchanged by this commit.
