Quick Settings volume control (to preserve hardware volume buttons)

Hello,
First of all, I want to thank you for the wonderful app — it works better than many other lock screen apps out there.

I’m opening this issue to suggest adding a Quick Settings volume control. I’m not sure if this goes against the project’s vision or not, but I’d still like to explain why I’m proposing this feature. I think many people want to use double tap, QS tiles, or widgets to lock the screen because:

1. It’s more convenient.
2. It helps extend the lifespan of the physical power button.

The same logic applies to the volume buttons, I’d also like to press them less often physically, especially when I need to adjust the volume frequently.

As for why I’m suggesting this in your app, despite there being many other apps that already offer this feature —
When I started using your app, I noticed that the lock screen you coded responds faster than anything else, and it feels like a real pleasure to use. That’s why I thought that a Quick Settings volume control written by you, by your code (even as a small addition to TapLock) would be a very nice extra.

And yes, this is just a request; the decision is, of course, up to you. Thank you for your attention 😌

No files, tests, or entry points are named in the issue. First inspect the Android project for existing Quick Settings and volume-control entry points, then clarify the tile behavior and acceptance criteria before estimating implementation; done should mean the requested control works without relying on hardware volume buttons.
