📄 Description

Route hardware volume keys to Cast via MediaSession VolumeProvider
Use CastSession.volume (0–1) mapped to 0–100; clamp and step by 1
Update provider with actual device volume after each change (prevents stalls)
Drop stream-volume/polling attempts and other leftovers
Expose get/set/adjust device volume commands to the player

Brief summary

Currently when you try to change the volume while casting, it changes the volume of the phone/tablet. It's very inconvenient as you need to find a remote to change the volume of the receiver.

Which issue is fixed?

Fixes #584

Pull Request Type

Android/backend

In-depth Description

Not sure if it's the best solution, but it changes the behavior of the app to the desired one. It tries to change the volume by 1 and if it's not supported, increases the treshold.

How have you tested this?

Install the APK, cast -> try to change the volume.
