Foreground Service on Android

**Is your feature request related to a problem? Please describe.**
On Android the communication is interrupted after a few minutes Minutes when the app (Ionic/React) is in background. This comes from the Android OS power saving. On iOS this is not the case when BLE service has the permission to run in background. On Android the BLE service needs to be moved to a foreground service, otherwise it gets interrupted. For applications which need to stay connected in background to acquire sensor data for example or want to do a reconnect if the ble device gets lost, this is not currently not possible.
When the app comes from background, it seems that all the messages are spit out at one time, overloading nearly my backend. So it seems, that somehow it is running in BG, but the callback is not thrown.

**Describe the solution you'd like**
It would be great, if there would be a function to put at least the callback of the startNotifications() service into foreground, that we can still send and receive ble packets to the client. This would be also great for the scanning function as well as connect and disconnect if the connection of the ddevice was lost and to be able to do a reconnect in background.

**Describe alternatives you've considered**
I was looking into the https://github.com/capawesome-team/capacitor-plugins/tree/main/packages/android-foreground-service
plugin, but it seems it is not suited to do the task.

**Additional context**
Here it went into "standby mode":

Here it comes out of the background:

No files or tests are named. Start by reviewing the repository's Android BLE implementation and the referenced capacitor-plugins foreground-service plugin, then determine how background notifications, scanning, connection recovery, and reconnect callbacks are handled. Done means the requested BLE operations remain usable in Android background mode without delayed callback bursts.
