The customer app now uses the same halobestie_notif.ogg as the mitra
app (shipped in the previous commit). Channel ID unified across both
apps so backend FCM stops branching per recipient.
- client_app: same channel bump (chat_messages → halobestie_chat_v1)
+ RawResourceAndroidNotificationSound binding, both at channel-
create time and per-notification details. .ogg copied to
client_app/android/app/src/main/res/raw/halobestie_notif.ogg
(same 32 KB asset, identical file).
- Backend: drop the per-recipientType channel ID branch; everyone
targets halobestie_chat_v1 now.
Verified on emulator-5554 (customer): dumpsys shows the channel
bound to android.resource://com.mybestie/raw/halobestie_notif.
