Add controls option to media player playback card feature

[MindFreeze]

Proposed change

Add a controls configuration option to the media player playback card feature that allows users to choose which playback controls are displayed and in what order.

When controls are explicitly configured, each selected control is rendered as its own button in the specified order. When no controls are configured, the original default behavior is preserved.

Available controls: turn_on, turn_off, media_play, media_pause, media_play_pause, media_stop, media_previous_track, media_next_track.

Also includes a configuration editor for the feature (with multi-select, reorder support)

Would it be possible to have the additional option there for volume + and volume - button?

For the time being, if you want to have both media control and volume control, you need two lines, thus you canot have it "inline".

To have (on/off) (play/pause) (volume -) and (volume +) on the same line would be very versatile and not completely crazy from UX perspective.

This PR allowing to chose the button could make it possible.

I did consider that but it would have to be a separate PR after this one goes through. Adding them to a "playback" feature by default doesn't seem great but as options for customization should be ok

Exactly. As option ( not displayed by default) it would be great !

In this PR or another one, but this pr allowing to chose what to display is an enabler for this option !
