Improve power status for PowerState capable TVs

[starkillerOG]

Tested on a Samsung S95C.
Before the power status would turn on just after the TV was already off, it was unreliable.
With this change the power status is 100% acurate.

Based on updates of the build in samsung tv integration.

I was having issues with the power state on my S90C where once it was turned off it would no longer update until I reloaded the integration.

Tested the code changes on this PR and it seems to have fixed the issue! @ollo69 could you please take a look at this PR? 🙏

This PR seems like it works for me (same symptom as @starkillerOG ).

Works on S95B. @ollo69 can you merge this pls?

So far very early days but works for me on 2x QE50QN90CATXXU 50 TV's was having the issue on both. I would set the TV's up, it would initially show the tv status as on. Then power off the TV, then turn the TV back on. At that stage I would just get an off status reported in HA

Now I can power the TV on either from the remote. Hope this gets added in as it seems to be working well, without having to change the default port!

@Collo69, it would be awesome if this fix could be merged!

Any progress on reviewing this PR? It appears to fix a major pain point.

@ollo69 could you take a look?

@starkillerOG Thank you! I can confirm that your update fixed this issue for me on a 2024 Frame TV with Firmware 1201. I am still having issues with Art Mode - to which I posted a proposed solution in the issue.

I may create a new issue for that, once this one gets merged / resolved. Thanks again!

I can also vouch for this fix solving my issues.
