Always set pause feature on Music Assistant mediaplayers

[marcelveldt]

Proposed change

In a previous release we have strictly tied the HA media player features to actual player capabilities reported by Music Assistant players (which are rather dynamic given the broad player support of MA).
This works well except for one thing, which is pause support because the MA user interface does not distinguish between a player that does (not) support pause, it will silently use stop under the hood with a resume point. So this causes some confusion for users because in the HA interface they can suddenly not use pause anymore for players that do not support it.

After a bit back and forth discussion we decided that its best if the HA pattern follows the MA behavior so it feels more natural to a user.

Background story can be read in the linked issue report.
