Fix stream stats toggle not hiding diagnostics overlays

[ck13ptcg]

Fixes an issue where the Show Stream Stats setting did not fully disable stream diagnostics overlays.

Changes:

• Makes Show Stream Stats the visibility control for the compact stats HUD.
• Hides the Connected lifecycle badge when Show Stream Stats is disabled.
• Keeps existing behavior when Show Stream Stats is enabled.

Tested on Apple TV:

• Show Stream Stats Off: no stats HUD, no Connected badge.
• Show Stream Stats On: stats HUD and Connected badge visible.

Note:
While testing, I found that pressing L + R enables the diagnostics overlay. That shortcut may be worth documenting in the README or Stream Settings UI.

Hello @ck13ptcg
Thank you for the pull request. I've been waiting for this fix (#5) since April, 27.
Seems like developer is not publishing his current progress on the project on GitHub. Not sure why, this is a great product and also free-to-use
Just for info: I've successfully built it with your PR and the issue is resolved. Can you also see my feature request #6?
PS: I’ve done it, thanks to grok. Will send pull request today or tomorrow

Sorry new baby is home. Life is busy approving now. Happy to add you both to the project to manage things while I'm away/out. I didn't realize people were actually using this as initial feedback was lacking.
